Christians why do you guys not believe in Bigfoot?

We have hundreds of footprint castings of Bigfoot, lots of photographic, and video image evidence, suspected Bigfoot hair samples, recorded vocal evidence of alleged Bigfoot, and MOST importantly THOUSANDS of eyewitnesses around the world, claim to have seen Bigfoot! All of this evidence, and yet you Christians still refuse to believe in Bigfoot. Why can't you guys just have faith in your heart, that Bigfoot is walking around, somewhere in the woods right now. :'(
