Bigfoot, Monsters Etc, made up, real? Options

I wanted to know, since all of these angels and spirits exist, does the chupacabra and bigfoot exist?

Actually bigfoots are giants with small torsos and heads. And because they were so small, it was easier for them to hide, while the real giants were eaten by dinosaurs. And in this way the evolution took the turn from "Surviving of the biggest" to "Surviving of the smartest", They had to hide for a very long time, this is why they are so good at it. And since the dinosaurs were quite stupid (they worked only on instinct level), it was easy for them to learn mind control - they learned to make beings "think they do not see them". So this is why they have not been found yet. And they are scared of people, because they sense (hear, smell the smoke, see the killings and cars and everything) the civilization arround them, but they have been hiding for a very long time and they do not know what it is, but they still fear it (us). They have noticed, that the dinosaurs are replaced by quite smaller animals, but these animals are actually smarter, that is why they still are avoiding them (us). You could say, that through evolution their instinct of self-preservation has got MANY times stronger than ours, that is why they attack and come close to people only when on brink of starvation or sickness, or, on some cases - when the people can speak to them mentally - through images (they can't speak) and show them, I'd say - encourage them, that this particular human is friendly to them. This takes very long time, but after a year or two first contact can be made. You could say, that - as whell as you fell comfortable, when you are in your home and noone disturbs you in your sleep, they feel comfortable if noone else disturbs them. This is because their senses (mental too) are MANY times sharper than many animals and men and they are disturbed by ANY not-forest-like sounds. This is because they have been hiding for centuries, even thousands of years.
About their bones - they are genetically strong and they have this thingy they describe (through images) as getting hotter and starting run faster when a need comes. I think, that they have something like adrenalin, that they can control whenever they want - not like us, when we get it only when in fear or attacking. The interesting thing is that when they use this ability, they show, that wolves are running away, but bears and dinosaurs (they still does not know much about rest of the world, so they still think they exist.) are drawn towards the bigfoots! I think, this is because of the smell of them, when the adrenaline rush is being used - the smell represents something big, but it appears, that the big animals love it. ANd i think, that they genetically are more "good" for eating than men, that is why the big predators hunt them. And when they fall, they are eaten to the tinyest bits.
It's quite fun watching the national geographic (IMG:style_emoticons/default/laugh.gif)
