There is no evidence that any species flora or fauna is exclusively native to this planet.
There is no more evidence any species evolved here than there is for them to have been delivered or engineered here by extraterrestrials (which theoretically, could be occurring unobserved in our midst if there is such an advanced extraterrestrial intelligence).
What do evolutionists think about teaching that life came from outer space??? They already teach the Big Bang theory, which is just another immaculate conception...
To claim life evolved here without influence from the rest of the cosmos is a claim that the earth is the center of the universe; this is akin to saying the sun revolves around the earth and the earth just magically appeared here.
For there to be life on earth consistent with evolutionary theory, there has to be life elsewhere and that life is in the same place of the cosmos the earth is from.
Evolutionists will mock creationists saying they believe in a flying spaghetti monster, but conveniently forget it is evolutionists that believe in a boiling pot of primordial spaghetti sauce... illogical...
(p.s. I am an atheist)
saying that to claim life evolved here uninfluenced by life elsewhere in the cosmos is akin to saying that the sun revolves around the earth is simply a non sequitur. And to say that "for there to be life on Earth consistent with evolutionary theory there has to be life elsewhere and that life is in the same place of the cosmos the earth is from" is just not true. Evolutionary theory explains life without such other influence.
"There is no evidence that any species flora or fauna is exclusively native to this planet." Nor is there any evidence there is life elsewhere.
I'm not saying that life is something exclusive to Earth. I'm just saying that it's existence here is not reliant upon its existence elsewhere. Think about it. If life on Earth came, somehow, from life elsewhere, where did that life come from? Life, whether on Earth or not, must have at some point come into existence, whether spontaneously (boiling spaghetti pot) or by the will of a supreme being (flying spaghetti monster). It's unavoidable. so why not on Earth first? (and please, note that I'm not actually advocating any one position. Life could have arisen (or arrived) on Earth by any one of many means, known and unknown, none of which have been either conclusively proven or disproven!)
