Well Redi disproved abiogenesis and he was trained by the Jesuits so your perverse implication that this iis a science vs religion thing is silly. And why do you say ‘creationist’ as if all evolution theories take species as a given?? You are really perverse in how you distort things.
If Darwin explained the development of species he never said where the first ones came from. Plus, logically, there is a grave illogicality in his theory (one you seem to hold):
from Aristotle to Darwin by Etienne Gilson
”” A more accurate title for Darwin’s book, according to Gilson, would be the Origin of Varieties. Darwin’s use of the word “species,” however, is contradictory. “To say that species are fixed,” Gilson writes, “is tautology; to say that they change is to say that they do not exist, Why does Darwin obstinately say that they transform themselves, rather than saying simply that they do not exist?” (pp. 140–144)”
