You may end up with male and female human beings in the end, but the theory has a big problem “In the beginning.” The only possible way, in my mind, to reconcile the “Theory of Evolution” as stated by scientists to the Biblical account of creation is to say God Created them male and female, and then they evolved.
The "big problem," though, is a problem only for the bible literalists - the mountains of evidence from biology all point to asexual life preceding "male and female" by at least a couple of billion years.
Scientists appear to be able to look at more evidence of the complexity of life and the universe than the average person will ever see. Why many do not believe in God, I have no idea.
The complete lack of evidence for any gods. And I say that as a former Christian, or at least a former missionary kid/Presbyterian/Episcopalian.
