You can theorize something originated from a black hole, but you have to explain where the black hole came from, you have to explain where gravity comes from, you have to explain where space itself came from, where matter to fill that space came from.

What is "it" referring to in the sentence "look, it's simple?"
The topic of this thread is simple but you're trying very hard to make it complicated. Biological evolution happened. That we don't know how life started and that we're not sure of how the Universe began is off topic and irrelevant.
Do you even doubt that evolution took place? If so then why would that be?

Both genders would have had to evolve simultaneously, but I don't see how this would be possible without assuming that two separate populations-- One which evolved into male and the other into female-- Came in contact with each other. But this is highly, highly, highly unlikely. Meh...

Martian answered your question very well. I will simply add that asexual reproduction does not necessarily produce offspring which are identical to the parents. Random mutations can and will occur that will make the child genetically different from the parent. This is how evolution occurs...
