Humans were created both before and after animals.
God created the Sun on the first and fourth days.
People fanwank their way out of these to have a book free of contradictions, but fanwank isn't scripture.
They had other children.
For the sun part, this probably refers to Genesis 1:3 "let there be light" and dividing day from night, and Genesis 1:16 "And God made two great lights; the greater light to rule the day, and the lesser light to rule the night" and often in between there's "morning and evening". The way this happens after the fourth day is with the sun and moon lights.
I wasn't there at the time, but I assume reality pre-day four was running prior to OpenGL 2.4 and was using global illumination, and then afterwards switched to RealEngine 4, probably. Just a guess.
Humans being created before and after animals likely refers to Genesis 1:26 and 2:19. That is a bit curious, agreed. The way I take it, since Genesis 2:4-29 happened after the 7th day, is something like "hold up, let's go back to those days when plants, animals, and humans were created, and get slightly more specific about it.
The origin story in the Bible is short on specifics, so it leads to a lot of interesting fan theories, and divides many of the staunchest fans. "These are literal days here" "no, these are phases, a day could be any length of time, the sun wasn't even there yet" and so on, as if that was the main point of the passages, when it isn't.
To be pedantic, the creation of the first day was light and darkness. The fourth day was the things that emit light: the sun, stars, and moon. I mean, it's still somewhat weird because it seems like it's inventing effect before cause, but the sun is very clearly not being invented on the first day.
The more fun contradiction is that Jesus' genealogy from David is given twice... and both of them are completely different.
It's one of many many flaws that made me question my (protestant) religious upbringing.
Uh...
