Do you believe that there are other worlds similar to the earth?

do you mean worlds in our solar system and beyond? with other life forms on? if so i think there are, i find it hard to believe that we are the only intelegent life in the galaxy, someday we may start space exploration and we may come across other worlds with other life forms on them though i doubt many of us will be around when that happens.

this is a little foolish, but I think (look at the full moon) the blue glows on the moon is actually water. I also think the reason the moon shines is because it is daylight on the moon... I mean think about it dores the sun only light one planet... I have heard they wanted to build a space colony on the moon, and I know for a fact the US gov. has secrets... just think the black hole cold be like a portal leading into other galaxies

definately the universe is so big that you cant say what it contains all are mere guesses i totally believe that there must be few ohter worlds which is similar to us

i dont think so....if ther is another world it will be good we got new neighbours...may be some day humans will conqure all this planet!

I guess there are. I have watch a documentary that shows earth is only a small dust outside the universe. So there will be more like us, which we called as alien.

yeah of course...the universe is a very vast space and there may be thousands if not millions of planets like earth and many of them may be similar to our earth like having living things on them.....
