Your comment indicates an understanding of science which has not progressed much beyond early elementary school

Oh?

Then why do so many PhDs in so many fields disagree with one another?

Oh, yes. You don't even understand logic.

Then why do so many PhDs in so many fields disagree with one another?

That's what we call "begging the question". Who says "so many" (how many?) people with advanced degrees in the natural sciences, but in "so many" (how many?) different disciplines mutually disagree? You assume, without evidence, that this is the case. Define your terms (How many is "so many"? Is that number significant? Why?) and then prove your assertion. Provide evidence.

Or just admit that you're blowing smoke.

BTW, the controversies over "global warming" and "evolution" show what happens when politicians and philosophers (I'm being generous) attempt to draw conclusions which exceed the scope of available evidence, and in fields beyond their expertise.
