Do you believe in extraterrestial life?

Lol, I tried to explain it without posting it.

That, or Reapers. And Kaiserreich.

But I really should fully read that article some time, it looks very interesting.

i believe that there is extraterrestial life, because the chance of there not being extraterrestial life is smaller than
the chance of existence of extraterrestial life.
stalin made a video about it.

Someone has to draw up a concept of a sentient plant.

edit:

@JosefVStalin

I bring you, ted, the sentient plant.

hello ted, do you want some cheese?

I'm pretty sure he has enough cheese on those, eye...things?

I never understood how could some one calculate the probability of life existing on other planets, considering we only know of it happening once. We haven't even explored planets in our solar system. All we know we could be alone, or the universe is full of life, but I doubt we will ever know.

Well, simple. We could assume that since there are 9 planets in our solar system and only one of the has life, that 1 out of every 9 planets has life. This would probably be completely wrong, but it is a way we could calculate the probability of life on other planets.

Well the thing is, that we don't really know if there is or isn't life on other planets in our solar system. We only closely explored Mars, and even that a very small part of it.

(I see now you addressed that)

But thats my problem, we have to assume way to much.

Well, we also assumed that the U.S. could never become a country, we assumed that Napoleon or Genghis Khan could take over the world, the point is science IS assumptions until it can be proven wrong.

Not even close.

Well, as Ronald will love to tell you, you can't judge the probability of an occurrence with a sample size of 1. Of course, he has an ulterior motive for hating aliens.

Personally I think it's a certainty that life exists elsewhere, and to assume otherwise is an unthinkable hubris.

The only good bug is a dead bug.

There are objects in our solar system that we believe are able to support life, for example Europa.
If there are objects that can, then the possibility of aliens is already high.

Okay, so let me put it this way. Do you, @JosipBrozTito believe that there is a higher chance that in the vast galaxy, let alone, the infinitely vast universe, that only a single planet in a small solar system at the end of a large galaxy, is the only planet that has life on it?

Irrelevant, but yes i do. I was talking about actually calculating the odds, what we have is just wishful thinking.

Well, Europa is an object that might be able to support life is in our solar system. If there are two objects that can in one solar system then there must be a lot of places able to support life, then imagine how many in a galaxy? Hell, do the drake equation and figure out yourself, if you find it necessary.

Like you said "might be able", it still doesn't change the fact we only know of one occasion it actually happened.

Right, and by thoroughly observing that one occasion, we've gained quite the insight on what a planet needs to be able to support life.

Still doesn't help in calculating the odds. Its still only one sample.
