Re: "Do you believe in aliens"

Aliens are everywhere on Earth. In fact aliens are so common there are only about two actual Humans on the planet.

They're hairy, have big feet and are known as Mr & Mrs Sasquatch.

Yep, I believe that there is life elsewhere other than on Earth.

I do not believe that aliens have visited Earth.

Re: "Do you believe in aliens"

Given the sheer scale of the universe, I think find it impossible to believe that life has not evolved elsewhere. Intelligent life? Almost certainly. Will we ever meet/hear from them? Highly unlikely.

True. Although that distance will of course increase with time. Can't predict how weak our signals would have to get before they couldn't be distinguished from background noise, though.....
The key to "communication" with aliens, either with us detecting them or vice versa is less about the content of the message and more about looking for artificial radio transmissions, which, if you know what to look for, stand out like a sore thumb. A broadcast of Happy Days 'looks' very different to background radio noise, even if the actual content has degraded beyond retrievability (and, in the case of Happy Days, probably for the best if we want the aliens to bother replying ) the repeating, ordered nature of the signal may still send up red flags with a passing alien.

Re: "Do you believe in aliens"

Use of "believe in" irks me too be it about this topic or something like evolution.

A remarkable number of things are "just right" on Earth, any one of which would make life impossible. However, with some 100+ billion galaxies each with 200+ billion stars each, it's rather unlikely we're the only ones with air, water and just the right amount of sunshine. I remember reading somewhere that there's a mathematical probability of 1 million 'earth like' planets in the Milky Way alone.

That gives me an idea to write a movie or TV show about some sort of space vehicle that visits other earth-like planets.

I shall call it "Wagontrain To The Stars"!

Hmmm, trillions of planets, trillions of stars, billions perhaps trillions of Galaxies. Do I believe in Aliens?

Well duh huh!
Exactly. The simple fact we are here lends credence to there
being other life out there. Even if it's so far away we never encounter
them in Human existance, they must still exist somewhere out there.

But I do believe they've been and are here.

Re: "Do you believe in aliens"

I figure by the time any signals are picked up from Earth it will be thousands of years from now. We are one tiny little planet in the middle of nowhere. For all we know aliens might live on the opposite end of the galaxay and we are the only life in this part of the galaxy so it would take million of years for our signals to reach across.

Even if some alien race does pick them up, they might not have the technology to respond or fly to us.

Here is a question that I have: How did aliens evolve so fast if they exist. I am assuming everybody started off on an equal footing at the beginning of time. The universe was formed and then life began on different planets.

How did one life form evolve to the point where they are able to bridge the interstellar void? Did they have supergenes emplaced in their DNA when they started rising from the goo of their planet?

I personally believe God created all life, but I would like to think He made other life out there also.

Re: "Do you believe in aliens"

Well if evolution is the theory, it could have simply started earlier elsewhere.

Simple as that.


Different Galaxies, and solar systems and planets form at different times.
The right circumstance come along at different times due to star type,
collisions with the planet etc etc.

It's very plausible that many other races evolved and advanced beyond us
before us. It's also just as possible we are more advanced than some or about
the same.

Radio signals travel at the speed of light.

The galaxy is 100,000 lightyears across. Ergo, it'd take 100,000 years for our signals to reach the otherside of the galaxy. Not "millions."

There's also some question as to whether or not our signals can make it much past the influence of our solar system before being blown back by the "wind" in the wide universe beyond our Oort cloud. Further, if our signals will even be distinguishable from the natural radio noise generated by the galaxy itself.
