Take this analogy
Man::computer
Force::life
Man has never made a living organism from something non-living and yet we desire to say a non-living force brought about life. How convoluted is that. Only mature life can reproduce. You cannot have larvae without a male and a female fly. And why is there a male and a female? Seems like we could easily through evolution just have one gender.
"And why is there a male and a female?"
Wrong analogy. Not all species have a male and a female. In fact, lower organisms are asexual and reproduce by fission or budding. Thank you introductory biology!
