[quote="Arani"]I think that there's some kind of land mass or island out there that contains these creatures. Things like dragons and Giants and such. Fairies and water creatures could proably hide well enough, and not counting Bigfoot. I can't explain how it's hidden, but I just think it's there. The creatures who strayed got seen and that's how we found out about them and that's what started making people believe or not believe. If they never strayed, we would have never known in the first place. Kinda stupid, I know, but hey, what the heck?

Satellites in Space can see everything. If there is a small island for all those creatures, it will be very different from everything else around it. And that will show up. If not by visual, then by infrared, or ultraviolet...
The only place not truly explored left on earth are the ocean trenches. But we already know what's in those...
