I went with the aliens. If there is an extremely advanced society around say Alpha Centauri they might conceivably send out a craft that can get there and back in a couple of decades.
Ghosts are extremely unlikely. It is highly doubtful that whatever might survive bodily death contains any trace of consciousness or personal identity.
ESP seems unlikely because there doesn't seem to be a mechanism by which any form of energy can be transmitted directly to the brain bypassing the senses.
I am highly skeptical of crypto-zoology because I believe it is highly unlikely that we will discover a land or sea based species as large as a dinosaur or even Bigfoot. The Bigfoot legend has been going strong for over 50 years indicating if it exists it is probably not a single being. It must be part of a breeding population that at one time must have been rather large. I don't think a community like that could avoid detection this long. Also correct me if I am wrong, but there is no such thing as New World Apes. How could Bigfoot have evolved in the Pacific Northwest?
