Still don't believe we are not alone?

160 Billion Alien Planets May Exist in Our Milky Way Galaxy | Alien Planets & Solar Systems | Planet Detection & Gravitational Microlensing | Space.com

I've personally never had any doubt, but when you multiply 160 billion times the number of galaxies in the universe, the chances for a civilization evolving almost *exactly* identical to our own seems pretty likely. Now, factor in civilizations that are not like ours.... just mind boggling.

Curious if there are still people out there that think we are unique?

I don't believe in UFOs or that other life forms similar to us have visited this planet during the past 100 years or so.

Maybe a much different type of life form that is not of flesh and blood .......

Mostly harmless.

It would explain tabs. Or some of the others on this forum.

This one is crazy enough. No more!

I think the odds are good we are not alone. I think the odds that we've been visited are extremely low.

[doug_porsche]

mathematically speaking it would surprise me more if we were the only life out there.

The problem is distance. A light year is a a very big distance.

yeh, it's a big universe

Not when you have warp drive. They just want you to think it is a long distance.

Actually, let me rethink that statement.

Where is ODDJOB UNO from?

The "math" would seem to suggest that there has to be life out there.

On the other hand, we don't know how odd it is for life to exist on a planet over the long time frames it has existed on Earth, and we don't know how likely it is for that planet's geology, weather and astronomical benevolence to allow life to evolve to the level we have. For instance, we've got a moon in orbit around us and two HUGE planets just outside our orbit which, together, sweep the cosmic debris that would otherwise regularly decimate our planet. While life is quite possible and may spring up often on planets, something tells me that hundreds of millions of years of relative environmental tranquility may be exceedingly rare.

Then, getting back to the math, I don't think science has really ever felt like it had a good explanation for how life would spontaneously occur. All life on Earth has DNA. The simplest DNA we can identify still makes a wrist chronograph look like a lump of mud by comparison.

Hmmmmmm.......

The numbers would appear to agree with you... too many other interesting targets for visitation

[genrex]

Maybe they've been watching transmissions of Galaxy Quest, thinking it's a documentary. That would be pretty cool.

Or a well set-up 944. Thank God such technology hasn't fallen into the hands or claws of a hostile life form.

Explain all these things seen in the sky by people (myself included). Obviously some are fakes, but obviously, some aren't. There is some really serious sheet going on in the sky.

[VaSteve]

The vastness of space is almost imponderable. It gives me a headache to think about sometimes.

[Noah930]

That's because your head is so small. Comparatively speaking, of course.

Yes, the odds are exceedingly low. But if the odds are 1 in a billion, then there are 160 planets in our galaxy with life. If there are 100 billion galaxies, a lower estimate, then there are 16 trillion planets with life in the universe.
