No doubt about it: There’s life out there — somewhere

It can be said of many retired people that we have too much time on our hands and too much time to fill our heads with goofy thoughts.

So, when NASA announced the demise of the Mars rover Opportunity the other day, I was filled with just a touch of sadness, but also with gratitude that the 90-day mission lasted 15 years and that NASA was able to collect mountains of data from the Red Planet.

My wife joked that Opportunity didn’t spot any “little green men” traipsing around the Martian surface..

Then I began thinking as I’ve done my entire life. I believe with every fiber of my being that there is life “out there, somewhere, deep in the void.”

I know what the Bible says about God creating humankind in his image. And I believe those words. I also believe the Great Creator was capable of placing life well beyond little ol’ Earth, an insignificant speck in the vast expanse of space.

I cannot even begin to grasp the size of the universe. I mean, “forever” is, well, a distance that none of us can fathom. I’ll just leave it at that.

Therefore, my limited understanding of statistical probabilities tells me that somewhere out there — way, way beyond anything we’ve ever laid eyes on — there must be a planet orbiting a star that has atmospheric conditions capable of sustaining life.

What does it look like? Beats me. Would that life necessarily be oxygen/nitrogen breathing life? Not necessarily. Does that life necessarily mean it is more advanced than we are? No. It might be mere vegetation. Or some sort of creature we cannot define.

Has this life visited Earth? I don’t believe for one second that we have been seen up close by any extraterrestrials.

Opportunity bit the Martian dust after fulfilling its mission far beyond what scientists had hoped it would accomplish. It didn’t see anything. Just remember: Even a journey of tens of millions of miles into “deep space” hardly constitutes a journey that covers the expanse of our universe.

Look at this way: How many grains of beach sand would it take to fill the oceans? Yep, it’s likely even bigger than that out there!

NASA finds another ‘Earth’

Well, how about this bit of news?

NASA announced it has discovered a planet that looks a good bit like Earth, orbiting a star that looks a lot like our sun.

The space agency has been hunting for this kind of scenario for decades. It means — maybe, possibly, potentially — that the planet, known as Keplar 452b, could be hospitable for, um, life … perhaps even as we know it.

That’s the good news.

Here’s the bad news: Keplar 452b is 1,400 light years away. How far is that? Well, a light year is the distance light travels — at 186,000 miles per second — in a single year. So, it’s 1,400 light years out there. That means, quite clearly, that we cannot get there.

Nor, one can assume, can they — if there is a “they” on Keplar 452b — can get here.

Then again, maybe they have come here and we don’t know it.

OK, I get that it’s not likely. Astronomers think the planet is in its rocky stage, which is a precursor supposedly to entering its “greenhouse” phase.

Still, this discovery is quite exciting.

I’ve long thought that the statistical probability is just too great for there not be life somewhere in our universe, given the known numbers of galaxies, solar systems, stars, planets and other orbiting celestial bodies out there.

How many gazillions of them are out there? Too many to discount the probability — let alone the possibility — of life.
