From Hamlet: There are more things on Heaven and Earth, Horatio, than are dreamt of by your P0hilosophy. By philosophy, Shakespeare was referring to science by the term it was then known.
That's what I believe. Some things that science would say do not exist, do indeed exist. Ghosts, vampires, reincarnation, afterlife, God, space aliens, bigfoot, the Loch Ness Monster... I don't know which one(s), but I acknowledge any of them could.
Reincarnation seems more likely than some, since it is believed by so many major religeons, including Judiasm and Native American, which are my ancestral religeons.
