Is there another planet earth out there, exactly like ours...?

...maybe humans weren't the dominant species on it, maybe there are still dinosaurs roaming it or maybe it is further in the future than us, who knows?

There are other planets similar to ours in shape and size but what exists in those planets no-one knows. I dont think we are meant to know neither are they for our eyes to see. Scientists can only prove they're other similar planets to earth but cant prove what lives on them.

There might be.
We may never know.

[shaneyboy]

yes and ur plugged into it.

[? jojo?]

uh actually there is it was on the news but to get there you'd have to be on a rocketship all your life then have kids who also have to be on a rocketship all their life and then their kids would reach that planet.

well if you belive Star Trek, theres 5 or 6 alternate Earths out there

[red cross white background]

no there isn't.
in fact there are no aliens,life in space,ghosts,life after death,etc

[ADICT]

There's plenty of dinosaurs roaming around this planet earth!

[Avondrow]

No

There may, indeed almost certainly are, planets similar to earth in terms of orbital radius, mass and composition. But to expect mirrored evolution of the biota, that is too Star Trek, I'm afraid!

when you consider the size of the universe anything is possible, infinite space gives infinite probability, i think there is a chance that there is a planet identical top ours somewhere out there.
