Skepticism is a requirement of critical thinking. But skepticism is not the same as doubt. And questioning everything does not mean placing equal value on every idea.

I agree, and I certainly don’t place any value on irrational ideas. Down with flatearthism!

It is skepticism that allows us to have a high degree of confidence in the substantial accuracy of most of today's core scientific theories.

I cannot agree with that. The core of today’s scientific theories, at least as accepted by the established order, includes a ban on even considering intelligent design as a possible explanation for existence. If we were created, then the fundamental belief of modern science is based on a falsehood.

To JohnD (and any others) for more specifics I’m happy to answer PMs.

No theories "include a ban" on anything.

Intelligent design is massively discredited and has zero supportive evidence. But anybody is free to investigate it. No existing theories of evolution stand in the way of such investigation. It would be accepted if evidence could be provided.

<<The U.S. National Academy of Sciences has stated that "creationism, intelligent design, and other claims of supernatural intervention in the origin of life or of species are not science because they are not testable by the methods of science." The U.S. National Science Teachers Association and the American Association for the Advancement of Science have termed it pseudoscience.

For a theory to qualify as scientific, it is expected to be:

• Consistent
  
  Parsimonious (sparing in its proposed entities or explanations, see Occam's Razor)
  
  Useful (describes and explains observed phenomena, and can be used predictively)
  
  Empirically testable and falsifiable
  
  Based on multiple observations, often in the form of controlled, repeated experiments
  
  Correctable and dynamic (modified in the light of observations that do not support it)
  
  Progressive (refines previous theories)
  
  Provisional or tentative (is open to experimental checking, and does not assert certainty)

For any theory, hypothesis or conjecture to be considered scientific, it must meet most, and ideally all, of these criteria. The fewer criteria are met, the less scientific it is; and if it meets only a few or none at all, then it cannot be treated as scientific in any meaningful sense of the word.

Typical objections to defining intelligent design as science are that it lacks consistency, violates the principle of parsimony, is not scientifically useful, is not falsifiable, is not empirically testable, and is not correctable, dynamic, provisional or progressive.

Critics also say that the intelligent design doctrine does not meet the Daubert Standard, the criteria for scientific evidence mandated by the US Supreme Court. The Daubert Standard governs which evidence can be considered scientific in United States federal courts and most state courts. Its four criteria are:

• The theoretical underpinnings of the methods must yield testable predictions by means of which the theory could be falsified.
  
  The methods should preferably be published in a peer-reviewed journal.
  
  There should be a known rate of error that can be used in evaluating the results.
  
  The methods should be generally accepted within the relevant scientific community.>>

<<The Pic du Midi Observatory (French: Observatoire du Pic du Midi) is an astronomical observatory located at 2877 meters on top of the Pic du Midi de Bigorre in the French Pyrenees. Construction of the observatory began in 1878 under the auspices of the Société Ramond, but by 1882 the society decided that the spiralling costs were beyond its relatively modest means, and yielded the observatory to the French state, which took it into its possession by a law of 7 August 1882.

The 8 metre dome was completed in 1908, under the ambitious direction of Benjamin Baillaud. It housed a powerful mechanical equatorial reflector which was used in 1909 to formally discredit the Martian canal theory.>>

Official Edgar Rice Burroughs Tribute and Weekly Webzine Site: Volume 3937

Edgar Rice Burroughs (1930), Fighting Man of Mars wrote: Upon the edges of plateaus that once had marked the shore-line of a noble continent I passed above the lonely monuments of that ancient prosperity, the sad, deserted cities of old Barsoom. Even in their ruins there is a grandeur and magnificence that still have power to awe a modern man. Down towards the lowest sea bottoms other ruins mark the tragic trail that that ancient civilization had followed in pursuit of the receding waters of its ocean to where the last city finally succumbed, bereft of commerce, shorn of power, to fall at last an easy victim to the marauding hordes of fierce, green tribesmen, whose descendants now are the sole rulers of many of those deserted sea bottoms.

<<Accurate placement of these ancient dead cities from the time of the Orovars required my creating an accurate map of ancient Mars/Barsoom with all those oceans in place. The great Hellas and Argyre Impacts that blew away most of the northern hemisphere, split open the Valles Marineris, and erupted all those immense volcanoes, are currently believed to have occurred around three billion years ago. Since Mars has no tectonic plates to move continents around and raise new mountain ranges, elevations would not have changed in the past several million years. Therefore I felt confident in using the MOLA Laser Altimeter Topographic Map of Mars to establish the basic sea-level (at MOLA’s 0-meter elevation) for the time of the Orovars. I superimposed the MOLA map over Shiaparelli’s 1886 Mercator projection map—which I turned over to place north at the top, and removed all of Shiaparelli’s place names.>>

Mädler and collaborator Wilhelm Beer produced the first reasonably good maps of Mars in the early 1830s. When doing so, they selected a particular feature for the prime meridian of their charts. Their choice was strengthened when Giovanni Schiaparelli used the same location in 1877 for his more famous maps of Mars. The feature was later called Sinus Meridiani ("Middle Bay" or "Bay of the Meridian"), but following the landing of the NASA probe MER-B Opportunity in 2004 is perhaps better known as Meridiani Planum.

Mädler lies in the south of Meridiani Planum, close to the prime meridian and about 10° east of Beer. Schiaparelli is also in the region.

<<Airy-0 is a crater on Mars whose location defines the position of the prime meridian of that planet. It is about 0.5 kilometres across and lies within the larger crater Airy in the region Sinus Meridiani. The IAU Working Group on Cartographic Coordinates and Rotational Elements has now recommended setting the longitude of the Viking 1 lander (47°.95137 west) as the standard. This definition maintains the position of the center of Airy-0 at 0° longitude, within the tolerance of current cartographic uncertainties.

Merton Davies tied this crater into an extensive geodetic control network of the planet Mars based on Mariner 9 and earlier photographs. The Mariner 9 Geodesy/Cartography Group proposed that the prime meridian of Mars be defined by the center of Airy-0, which was selected by Harold Masursky, Gerard de Vaucouleurs, and Merton Davies at a Group meeting on 14 August 1972.

It was named in honor of the British Astronomer Royal Sir George Biddell Airy (1801–1892), who in 1850 built the transit circle telescope at Greenwich. The location of that telescope was subsequently chosen to define the location of Earth's prime meridian.
