crop circles are frauds thats for sure. hell all you need are 2 peices of rope, and a plank of wood
but what Chris said makes sense. Homosapien sapiens have only been on this earth for an estimate of 15,000 years. I mean...hell dinosaurs existed for something like 200 million years.
(haha thats funny we've been on this earth for 15,000 years and we're already worrying about destroying our own world...man what were those dinosaurs doing right?)
but seriously some sort of life has to have to ability to reach at the least their end of the galaxy by now, I would just think it be naive to even think otherwise
