sick of religion.. let's talk aliens

As far as "aliens" go... we have evidence that:

Life originates on planets with atmospheres. We can get specific, but that focuses the search down to looking for "us". We're not looking for humans, so don't look for human-friendly environments.

These planets must orbit stars... they are the outside energy needed to make everything work. Earth isn't a "closed" system any more than a pot of water would be. There has to be energy for the process of life to begin and be sustained.

That's what we know from sitting at our PCs. We fall under those categories (we're life, duh ). Here's what we also know...

Planets orbit other stars. Our nine (Pluto is a planet, damnit!) aren't the only ones. EDIT: What is it now... thirteen? Twelve without Puto?

These planets have atmospheres. The Kepler telescope just imaged a planet and its atmosphere. Granted it's some four thousand degrees on that planet, but the important part is that it has an atmosphere and we know it.

These stars provide a wealth of radiant energy. Four thousand degrees of heat doesn't come from nowhere.

Given those facts, it isn't too far of a jump to presume that life can arise on other worlds. Will it look like us? Probably not. Evolutionary biology could take many different avenues given the planet's environment. Example: Flight on Mars. Earth birds couldn't even begin to fly on Mars... outside of lacking oxygen, the atmosphere is far too thin. Don't even think of a conventional airplane at that point. So if a planet with a thin atmosphere were to develop life, flight would develop very differently (if at all) given the environmental pressure. Different stellar classes produce different amounts of radiation and different planets "deal with" this in different ways which also mixes up the environmental pressures a tad.

All in all, given the data that's been coming in, life out there isn't very far fetched at all.

I can't remember what I was watching but it was a show on the discovery channel and it talked about the different possible world's, I only caught the end of it, but one of the worlds they described was an oxygen rich planet with a thick atmosphere in which it may be possible for much much larger animals to attain flight. It would be odd to see whale sized creatures floating about.

There are limitations to what sort of creatures might emerge, but the possibilities are truly staggering.

Do aliens exist?

Who has proof?

Jesus was a visitor from another world, was he not?

John 8:23
But he continued, "You are from below; I am from above. You are of this world; I am not of this world."

This idea of the divine extraterrastrial may not be so preposterous after all ... :scratchchin:

We have concrete proof that life can and does exist on a large rock orbiting a star. It happened on one out of one hundred said rocks orbiting this star. To date, we've located about 400 more orbiting other stars. If you take the percentage from your control (this star and its rocks) and apply it to the variables (your other stars and rocks), things start looking good for the whole little green men side of things. They only increase as more exoplanets are found.

Astronauts to the moon... HA HA HA HA HA!

Can you prove we're not? :whistling:

OMG! A wanna-be Carl Sagan!

"There are billions and billions of stars out there."

That's a new one.

Is that the typical response to being on the wrong side of the math?

What math is that, Maurice?

Funny you could pull Carl Sagan out of my post, but none of the actual numbers.

Try again. I'll be here

Why don't you be a good little boy and tell Daddy which numbers you are talking about? Daddy may not be as smart as his little boy.

Well, at least you admit the problem out the door, and since you insist...

Using a control source of the worlds we have explored, we have roughly 120 places where life could arise. To date, we have found exactly one. There are a few candidates, few places to look, but life's only confirmed in one place. This includes all nine planets (Pluto is a planet, damnit), their respective moons and the little guys hanging out in the nosebleed section... Sedna, Quaoar, etc. etc.

So 1 in 120, give or take. Less than a percent. Not too hot for the home team until you look at the number of planets outside our solar system that we've discovered. That's hovering around 400 at the moment, goes up a few every month or so. That's more than enough to hit a positive in a 1 in 120 chance. More than enough to hit it twice.

So if its sheer math you want, there it is.

Who gives a $hit?

Who gives a $hit?

You do, daddy! You asked your "little boy" to school your ass, and he did.

With the numbers put in front of you, in a plain easy to use fashion that anyone should be able to understand, you back off with no avenue for response.

I'll let you lick your wounds before we continue.

Class dismissed
