If you choose the amount of sticks you place on the ground in a forest, then are in charge of calculating the amount of sticks within a projected space and time... You are guessing at best. And you influence the the facts with contamination... Observance is the answer. Not contribution. You are brilliant. I thoroughly enjoy your videos. Also,  I would like to add something shared with me by a person of position at Rockwell, in Palmdale, California. We were in a Duck Hunting Blind together at Edwards Air Force Base when he said... "Don't you think it is awfully pretentious of us to assume or declare this to be the only planet with life on it?"
