I don't see any genetic similarities between chimps and fallen spirit beings. It would more akin to trying to mate with an amoeba. It wont be much fun and it will only anger the amoeba.
lol! It would certainly p!ss me off if I were an ameoba!
On the other hand, scholars of Genesis, Jude, and the Book of Enoch (sited by Jude) tell us that the human females and the fallen angels shared an overwhelming mutual attraction (and this is what caused the Fall).
The human-amoeba equivalency idea may be true but it requires making some rather large suppositions about what the heck angels actually are...and frankly without the Bible telling us about them we have very little to go on.
And, of course, if we listen to the Bible regarding angels, we have that inconvenient matter of it (the Bible) also being the very source of those pesky statements about human-angel interbreeding. And then, last but not least, there is also that unattractive story about Cain actually being the son of Satan.
Lots of folks seem to have trouble seeing their hands in front of their face, too.
I guess, given naysayer logic,
that means they have no hands.
