In regards to the anything is possible... How about you disprove it?

The abscence of evidence is not the evidence of abscence.

I am willing to wager that there are a shitload of things out there that we dont know about yet, that exist. Just because we dont know about it, just because we dont have evidence at this moment in time for or against it, doesnt mean it doesnt exist. It just means we dont know.

The evidence we have around us isnt perfect. It has been interpretted by an imperfect being, and as such, is imperfect. We can choose to take the evidence as truth, but that would leave us to such possible follies as the belief that the world was flat, or that the sun revolved around the earth.

With what we know now, yes, some things seem apparent. But so did they back then. Science is forever expanding, and as such, we will discover more that in time may very well make the things we view today as sure and fact to be just as silly as the earth being flat.
