If humans didn't kill them, where are they? And if they are all dead, how would something like that go extinct?
Those were recorded in different places *after* humans made contact with each other right?

It may seems impossible for humans to kill them, but doesn't it seem kinda unbelievable that humans could kill Mammoths? Creature that was a 100 times their size, but they were clever enough to drive them to fall off a cliff therefore killing themselves, but dead is dead.

Well, again, Saber-tooth tiger was a creature that could kill most things, and was probably viscous, not many things could kill it. Yet, here we are today with Old Saber-tooth on the extinct list.
