planet earth

[deethiem89]

Do you think that there is another planet out there just like us with cars and buildings, pet dogs and television?????????

[tubeway]

In an infinite universe there certainly is. The universe is finite but is so vast that there probably is a planet somewhere that is similar to ours

[Loosehead]

Yes many thousands of them I'd imagine.

It would be very arrogant of us (typical human race...) to presume we live on the only inhabited planet in this or any other universe, wouldn't it? But it would probably be very unlikely that, unless any other planet has the same density as ours, and was exactly the same distance fron its sun (to the split millimeter) and that its sun itself was exactly the same size etc as ours that life on that planet would be anything like life on Earth. In other words, "yes, deethiem89, but not as we know it......"

If God had created the universe all those 13 billion years ago our Earth couldn't have been in mind as our sun which is half way through its life cycle is only 5 billion years old. Why would it take 8 billion years to come up with his idea? I suggest life was created during these 8 billion years on a distant planet, that planet evolved and died. The highly intelligent race needed a new environment and chose Earth. So in another 4-5 billion years our Sun will be extinguished and we will need to find another planet and so on.

Kwicky, I'm not sure that people from space settled permanently on earth in the past, but I certainly believe they came here and cross-bred with the people of earth. That's where the legends of various 'gods' come from - including the god of the bible. I think he was someone from space.

NO, not just like us. If there is life on another planet it is most likely to be in a form completely foreign to us.

As has already been stated, humans have only occupied the Earth for a mere instant in ecological terms. For the vast majority of the time that life has existed on Earth, it has been in a simple single cells form. To expect another planet to have evolved in exactly the same way as the Earth did is unreasonable.

[naomi24]

wildwood, how can we say what beings from other planets might be like? Some may be completely 'alien', others may not. We simply don't know.

[BIGDOGY]

no!!!

[naomi24]

Bigdogy, how do you know?

[jollygreen]

I don't think it would be the same but I have absolutely no doubt that life exists on planets elsewhere in the universe.

That life would have evolved to it`s own specific environment and could either be well behind us in evolutionary development or well ahead of us.

Having said that, the chances of there being life on a planet with a very similar enivornment to ours and for that life to have evolved the same way, at the same rate and at the same time are very small but not impossible.

How about "Inner Space".
The solar system resembles an atom, The sun = the nuclei and the planets = the electrons.
Is it so hard to envision individual atoms as miniture solar systems. If so, then the chance of a doppleganger earth would be infinite.
Something to be considered whenever an atomic device is detonated ?.
