It's written later on that they also had other sons and daughters in addition to the original 3

The Bible does this a lot lol it has me wondering
It's usually just names a few important children and then says "and they had other sons and daughters"
People lived for almost a thousand years back then, and they also knew they had to populate the earth since it was so new so they had loads of children

Incest

I thought they only had 2

Me too

Yeah
