Rich, you make a very good point. I'm sure experimental military aircraft are misidentified as UFO's but not all UFO's can be attributed to military aircraft.....

I think the odds are in favor of it. As I've said previously the potential for some form of life exists in our own solar system. If it happened here on earth it can can happen elsewhere. There is an incomprehensible amount of places life could form.

While it is true that if it is possible for a thing to happen, it will happen given enough time. We are proof that intelligent life is possible, but I think you need a lot of zeros after the number to calculate the odds against intelligent life forming twice.

Are "we" truly intelligent??? Sounds like more human arrogance to me. We keep finding basic life in impossible places and space is just another place. And some of those places might be more hospitable then "here".

And yes Richard, I saw a silent Helicopter back before they were "known". It flew right over my brother and I one night. We saw many things up in the wilds of Maine with a small, very important, Navy base right in the bay with us.

There is a lot of zeroes, that's really the point. How many grains of sands on every beach on earth? That's the example that is often used to give perspective on the estimated number of suns we know of. They can have X amount of planets that can have X amount of moons either of which can support life. The numbers are staggering.

There is lot of things that make our planet special, firstly we're in a solar system that is the odd ball. Most of them that they are finding do not have planets with stable orbits so you're going to have wildly fluctuating temperatures etc. We're in the godilocks zone, it's not too hot or too cold and water is liquid on most of the planet. We have a Jupiter, Jupiter protects the earth from asteroids. We have a very large moon which is not common, that stabilizes the rotation of the planet giving us seasons.

There is lot of things that need to happen if you expect to find another earth type planet or moon but again due to the amount of stars....

If life happens, then it will tend to expand to locations other than where it originally formed. Some of the other locations will likely be less hospitable, and random evolutionary adaptations will eventually aid the expansion. Intelligence is a highly-effective adaptation for many situations, and therefore will be favored by evolution where other (physical) adaptations fail. How many zeros that requires, I have no idea. :o

Are they random? I've heard one theory about what alien life might look like. Within a different environment fish will still look like fish but have a different biological makeup inside adapted of course to that environment. Consider that dolphins look nearly the same as fish, they are completely different inside but almost identical outside.

You're right. My choice of words was not good. What you are describing is called “convergent evolution”. What I meant was, the MUTATIONS themselves are random. Some mutations improve a creature’s adaptation, some worsen it. Overall the individuals with beneficial mutations tend to survive to pass their mutations on to their offspring so the new adaptive trait becomes common in the species.

Speaking of dolphins, they and porpoises and whales appear to have higher than average intelligence. But they are so perfectly adapted otherwise to their water world that there is little or no environmental pressure toward even-higher intelligence.

Some argue that they are on a higher intelligence plane than man. Their reasoning is that they, in contrast to man, don't destroy their environment...

I can't remember the last time I saw Flipper operating a powered watercraft....you would think if he had developed more than man, he would no longer need to swim, like man no longer needs to walk.

How is that for reality, or am I delusional?

No, you aren't delusional. Your point of reference is just different than mine. And that's ok...

I think my point is best stated by Thoreau, "A man is rich in proportion to the number of things which he can afford to let alone." One can easily replace "rich" with "intelligent".....

One step further, who is more intelligent? a highly technological people who destroy Earth Mother or an indigenous people who live in harmony with it?.....

It's not our intelligence, or lack there of, that is destroying the planet's ecosystems, it's our sheer numbers, which have been made possible by our intelligence.
