Why haven't we discovered another form of life after 10,000 years of existence?

Answer 1

Okay, we are finding and discovering new forms of life all the time with new technology. There are new marine animals found with the deeper we are able to explore. Animals, bacterias, all forms of life are mutating and popping up all over the world. On mars, they've discovered water on the planet and plant life under the surface of this water.
Okay, so it's not Star Trek yet. We haven't communicated with alien beings...that we know of. But that's not specifically what you asked now, is it?

Answer 2

If we ever discover evidence of extra-terrestial life, it will probably be from picking up some sort of radio transmissions from outer space. We may never encounter evidence of other life forms in our lifetime even if our universe is filled with multiple inhabited planets for several reasons. The first is distance. The closest inhabited planet may be hundreds or thousands of lightyears away, meaning that any radio emissions may not reach us for hundreds or thousands of years. Also, since the universe is so big, we would need to be listening for these transmissions in the appropriate part of the sky at the right time. Also, even if there is life right now on an inhabited planet that is relatively close to Earth, the dominant species may be hundreds or thousands of years away from having the technology to produce radio waves. Even if we make contact with an alien civilization, imagine the difficulty with communication. Even if we spoke the same language, every time we sent a question, we would need to wait hundreds or thousands of years for a response....and vice versa.

"Hi, how are you folk?" we would ask. The reply would come ten thousand years later, "We're good....you?" By that time we may have nuked ourselves back to the stone age, civilization would have restarted again, and the new human race would get this message, and reply back "Huh? You talking to us?"

And forget about ever actually meeting these aliens, since any spaceship from us or them would probably travel slower than light speed.

Answer 3

For the first few thousand years we have been rather busy just surviving, first against nature and later against each other (which by the way is not complete yet). Only in the last few decades or so have we developed the tools necessary to travel to other planets, and only a small portion of the Earth's civilizations have this capability. I've no doubt that life is as prevalent in the Universe as virus's are on Earth.

Answer 4

Compared to the age of the universe, 10,000 years is nothing. If the age of the universe were the empire state building. The age of man would be a nickel on the very top of the antenna.

Answer 5

The universe is a big place. We may never discover any other life forms. Then again, you never know.

Answer 6

A few years ago we did find scientific evidence within a rock specimen on Mars which contained the fossil of a micro-organism. Even if it was a single-cell amoeba, from what I know about science.........that's life!

Answer 7

Get the latest issue of SEED magazine - Apr/May 2006. There is a good article in there about this topic.

Answer 8

We've only had the technology needed to detect extraterrestrial life for maybe 100 years...

Answer 9

because we think there are more important things to discover like.. things on the planet we live on.. like fish in the deeper parts of the sea... and animals far into the rain forests...

but id rather be sending things to other planets than ours.. theyre just so much cooler.

Answer 10

because we still dont have a ship that can travel carrying humans and go far enought to find another form of existence
