Evolutionists make the fallacious assumption this planet is the staring point for all life and is the encapsulated center of the universe unaffected by anything (or anyone) beyond it. It is akin to saying the sun revolves around the earth.
Not at all scientific of them; it is a faith based theory no different in logical fallacy than creationism in the ‘appeal to false authority.’
Actually, not at all. Most evolutionists assume that life on earth originated on earth, but a few think that life originated elsewhere and the earth was seeded with primitive organisms that originated somewhere else. They will agree that it's quite possible and even likely that life has also orginated on other planets, perhaps on many of them. I doubt any of them would be silly enough to say that the earth is the center of the universe. And how can you state that the assumption that earth life originated here is fallacious? That would require knowledge on your part that life on earth originated elsewhere. You don't have this knowledge, so you are making an assumption yourself.
I'm not sure what you are trying to say in the second part of this statement. Are you saying that scientists think that the earth is unaffected by anything outside its atmosphere? Because that is certainly a fallacious statement. I suppose you are saying that they assume the earth is not affected by anything outside the universe. I find it odd that you think that this is an unscientific assumption. . . We are unable to probe anything outside the universe, and science deals only with what can be examined. Influences outside the universe fall under the realm of philosophy, certainly not science.
I hope you're not suggesting that scientists should entertain any prospect, no matter how bizarre. For instance, maybe all celestial bodies rest on the backs of humongous, invisible, undetectable turtles? Would it be unscientific to discount this as a scientifically verifiable possibility based on the absence (and indeed unattainability) of evidence?
