Question about birth and how we made it here

[ineedmoneybad]

These might sound like a stupid questions but I'm serious. I've never studied this stuff or talked about it with anyone.

Where do we come from? Mom, dad or something else?

Were we meant to be born?

Do we come from a unique sperm?

Would we still have been born no matter what sperm made it in the egg by the same two parents?

Would we still have been born but look different if one of our parents were someone else?

If a differnt guys sperm went into the egg would we still have been born but look different?

If dads sperm went into another women would we be born from that other women?

If the exact unique sperm that made us went into another women, and she got pregnant from it would we have been
born?

Could I have been born a female instead of male?

Thanks for any response
