Dose the present world we live in contain signs of another world ? I have just been told it dose?

Who told you that? Don't listen to them! It's radical thinking such as this, that has led to all these major scientific discoveries... like 'the earth being spherical, not flat"; and "the earth revolving around the sun, instead of the other way around". Keep it simple, dumb down! ... or you risk being labeled a 'conspiracy theorist'; or worse still, a "truther". (In today's world, where 'truth' = "bad"!) LOL

P.S. - It's "does", not 'dose'. A dose is like a measured out amount of medicine, or illegal hallucinogenic drugs, one might consume at a time. I'm pretty sure you meant 'does'.

What do you mean by "signs of another world"? Who told you? On what evidence did he/she tell you?

Several planets in our solar system can be seen to have signs that water has flowed on the surface of them thus that primitive life (e.g. single-cell organisms) MIGHT have existed there at some time. But there are no signs of advanced life ever having existed on any of the other planets.

Our planet is the only one in the "Goldilocks Zone" - not too hot, not too cold - for advanced life. As far as all science and archaeology tells us, life on Earth has slowly advanced from single cell organisms through many variations and set-backs to life in all its variety as we know it now. "Another world" might imply other civilisations different from the present evolved human civilisations - so far no evidence of such "other worlds" has been found on Earth.

an alien world ---?? No.

but signs of past civilizations right here on earth? Oh, absolutely.

Not aliens.........but earthlings....... from way before our most distant recorded history.

I don't understand what that means.

but there's alien structures on the moon.

No,not at all,but we have fossils,relics etc of ancient people,animals and birds

No , is the short answer .

does, not "dose".
