Objectivist philosopher David Kelley might call this an example of the fallacy he calls “concept stealing.” That is to say, in order to entertain a theory of the universe being brought into existence by one’s thought, one must first assume that one exists to have the thought. But then where did one come from in the first place?
As to the puerile observations advanced as evidence along the lines of “Wow! If such and such were just a little more hot/cold/dense/light/you name it, then life would not exist, consider the Powerball lottery. The odds against any one person winning are vanishingly small – but someone always eventually wins.
Because this fallacy reappears in all ages, I assume there must be a certain sort of narcissistic personality type which so fears the prospect of a world without him (i.e., facing mortality) that he is drawn to these crank philosophies.
