Is there any "proof" or "hard evidence" that the vastly different stories little children tell are their imaginations?
Or is "proof" or "hard evidence" only demanded from those who believe in reincarnation, that is in past lives?
I 100% believe in reincarnation.
I have no idea if any of the stories are true or imagination, but I wouldn't write them off as imagination straight away. I would try to find out more, but only from what the child says naturally without any prompting.
I have see many comments saying that since there are far more humans now than before, they couldn't all have had past lives.
That opinion ignores at least two things.
First, it is the soul which reincarnates, not the body. According to some beliefs, the soul can reincarnate into any species, not necessarily the same as their previous life.
Humans here have increased, but what about the billions from other species which have died?
Second, what if there are humans in other parts of the universe who could be reincarnating here for whatever reason?
