What do you think?

 Sasquatch

It is a matter of belief; I have always, and will always believe   Sasquatch / Yeti live, because nobody has positive proof does not mean they don't exist; a few months ago a fish turned up in Japan that the world thought had been extinct for over 500,000 years, at least.

There is a story of a monk who lived on an island off the coast of Scotland for over 80 years, living off nuts, and berries.

This will cause some thought, and a little annoyance, but consider this.

Think of how many people believe in Jesus without questioning the story.

Here you have a man who was nailed to a cross for three days, put in a cave to die, and mysteriously vanished; which is more believable?

A creature can live in forests, or mountains without human contact, or a man can come back from the dead after being nailed to a cross for three days?
