Extraterrestrial-sm is a theory of life on Earth, which states that Microorganisms from an asteroid collided with the Earth, and, in contain with our eco-system, flourished. This could explain how life came to be on earth.
This theory has recently found new evidence, as found in This article. It states that water has been found on an asteroid. As well all know, water leads to life.

Considering intelligent life on other planets in VERY VERY UNLIKELY. Life that is super advanced?
Okay now for the likely hood of intelligent life on other planets.
Using our galaxy as a base there are about 100 billion stars. Now the number of galaxies out there is estimated at around 125 billion. So let's estimate that each galaxy has around 100 billion stars each.
That's roughly 12,500,000,000,000,000,000,000 stars. This is being very conservative as well given some estimates go as large as 400 billion just in our galaxy.
let's say for the sake of argument only 10% of those stars have planets. That's 1,250,000,000,000,000,000,000 planet supporting stars.
now let's say only 1% (likely higher) of those has a planet with the potential to support life.
That leaves us with 12,500,000,000,000,000,000 potential life baring planets.
Now let's say there is a 1 in a million chance that the planets that has the potential does develop life. This gives us 12,500,000,000,000
Let's really give life a hard time and say it's 1 in 10 million chance that intelligent life develops. Leaving us with 1,250,000 sentient life forms in the universe.
Now let's say half of those managed to get at least as far if not further advanced then we are without killing themselves in the process. This leaves us with just 625,000 sentient life forms in the universe.
Finally let's say only 1% of those 625,000 developed more advanced technology then us. This leaves 6,250 alien life forms more advanced then us, and this is being really conservative with the numbers of stars and generous with the odds.

Thank God that Asherlee and Mage came to back me up, as I was getting REALLY tired with my opposing side's "science". And thank God again that Mage did all the stats as I was actually going to do those but you saved me a LOT of time.
personally, I am not sure about extraterrestialism. I do not believe any of those crazy theories most people spout about them, but at the same time it seems as though there should be others out there...
What we are seeing in asteroids and interstellar dust are basic amino acids which basically organic proteins contain key ingredients for forming life.
Not what I was referring to?

That's an extremely minute number compared to the one you began with; you also forgot to factor in the chance of intelligent life even arising.

Shut up. You never had evidence for you points and you kept complaining about the same thing.
Your argument about the evolution on other planets fails because, like my argument, cannot generate enough proof neither can yours because we have no evidence for evolution other than on Earth.
As for the Asteroid's as the last line of Asherlee's article states that it is still un-known how the asteroids can retain water. I'm not saying your wrong but there's a lot of questions about the validity of the idea.
At least Samy and I (mostly Samy) were trying to rationalize with what we knew.
That's an extremely minute number compared to the one you began with;
Yes it is, that's why I don't find it all that likely that aliens made us. Though keep in mind the actual odds are likely higher considering the most basic thing you need for life is a liquid that will allow the base compounds to interact and mix.
you also forgot to factor in the chance of intelligent life even arising.
No I didn't.
"Let's really give life a hard time and say it's 1 in 10 million chance that intelligent life develops. Leaving us with 1,250,000 sentient life forms in the universe."
Anyway back tot he OP. What we are finding in asteroids are amino acids. While providing key components for life. A potential planet bombarded with such material might end up with higher odds of developing life this doesn't mean it was required.
Carl Sagan does a good job with the Drake Equation as it applies to only our galaxy. There are billions and billions of stars.
According to him, depending on the percentage of civilizations that eventually destroy themselves with their technology, there can be either as little as 10 or as many as millions of advanced civilizations in just this galaxy.

Yeah he did a good job with it. Also just to show how much of a hard time I was giving it all I for the sake of argument only used 100 billion stars per galaxy. While his estimate came up with 400 billion just in ours. So the staring number of how many stars are in the universe are likely 4 times what I started with, if not more.
To samy: What you said about how they don't know how water gets on asteroids is irrelevant. It matters not HOW but the fact that it IS.
