That is a very bold declaration.
Within the boundries of my own ability to think in linear terms, and personal human experience, I would be inclined to agree. That being said, that exposes a serious limit, or binding, as to my own capability to create and imagine. That's nothing to be proud of. But hey, the 70's were hard on me. What can I say?
On the other hand, I appreciate those pioneers down through history, with the talent to dream and imagine beyond the boundries of simple human thought that Trebor and I seem to share. For without them, who would have ever thought of workable electricity? Space travel? Medicinal advances? Just 30 years ago, the simplest of surgeries were more times than not life threatening. They say we even made it to the moon. I would have never thunk it. Not me. No siree.
If I were to have considered such possibilities further, I suppose I would have to concede that in this "infinite thing" that we call "everything," there could possibly, and more than likely, exist a species a tad smarter than we are. Perhaps even capable of trans universal travel. Who knows? They might even be able to explore this very planet as well as any of them.
We made it the moon, right? You think you could have convinced someone of that 100 years ago? Ahhh yes......it's sinkin' in now huh?
But, alas, I'm stuck here trying to reinvent the wheel instead. History will record me as one who thought the Earth was flat should any planetary visitors ever actually arrive here on our soil. Us Flatlanders didn't look that stupid until they proved the Earth round.
Sometimes I think, usually after a glass of wine or two, perhaps an unknown species could have possibly been here before. Who's to say that there are not civilizations out there millions of years more advanced than ours? Or millions of years under-developed? Not me. Then I sober up.
Besides, I have more important things to ponder. Like shoveling the driveway.
