Evolution needs millions of years to get things right – if reproduction is not right the species dies out after one generation.
How did sexual intercourse evolve?
The process of reproduction is amazingly complex and must have been perfect right from the beginning to be successful.
Is it really something that could evolve by chance over millions of years before it became successful – surely everything would have died out before it had became successful?
I suggest that the ability to reproduce was put in place right from the beginning by God the great Designer.
