We've had this conversation before. I was born remembering a previous life; those memories were extremely vivid until the age of six or so. That's my basis for believing in reincarnation.

My take on reincarnation is that lifetimes are like classes and that individuals... let's call them souls... have agency over what they learn. Or possibly there is only one soul weaving in & out of the lifetimes & consciousnesses of all living things.

You don't have to believe in reincarnation! I don't proselytize.

But neither should you. 😀
