How many times has the earth repeated itself?

[bigjoester99]

I've always wondered this: how many times has the earth repeated itself? How many times have there been humanoid life, or something close to it? Have past civilizations more intelligent than us left the earth?

Where the great pyramids built by a past alien civilization? I'm all ears.

[Corporal Clegg]

In case you didn't know, the Egyptian pyramids were built by EGYPTIANS...

[Bendy Demon]

Every artificial structure on earth was built by humans, not aliens.

We actually have always been quite capable of doing these things ourselves.

[bigjoester99]

Actually, I didn't say anything about the pyramids being Egyptian.

Isn't it fun to be redundant and repetitive

[bigjoester99]

Sorry

Sorry

[Corporal Clegg]

When you said Great Pyramids, I assumed the Great Pyramids were in Egypt... Aren't they?

They're in present day Egypt, but it probably wasn't Egypt back when whoever built it did.

we should stop spamming up the thread

[Rlyeh]

It repeats itself every year

And the Empire state Building was built by Daleks

Why can't our ancestors have reached a level of intelligence or have been just as intelligent, many times in the past, as we our today and build those monuments? Why does it haft to be aliens that started it all?

1. "Earth" does not repeat itself. It's a ball of rock some many billions of years old.

2. There have been several proto-human species that died out.

3. There have been no "more intelligent" civilizations. Some simply had more time and interest in things we do not.

4. There is no evidence of anyone who has permanently "left earth"

5. The pyramids were built by Egyptians. A past human civilization.

They're in present day Egypt, but it probably wasn't Egypt back when whoever built it did.

It was Egypt. Even in antiquity.

Now you're being really silly....You know as well as I do that Daleks can't climb scaffolding!

[Corporal Clegg]

We second-generation Daleks can climb, swim, and do backflips! *We* built the Empire State Building!

It was on TV and everything so it must be true

[Sir Smoke aLot]

No one can tell but i am sure it is ongoing process. Maybe after we research all the oceans depths and dig deeper we will find clues. One more thing comes to my mind - we know that Earths crust is 'regrowing' all time and maybe all traces of long gone civilizations are melted in the sea of magma.

Only if they were non-human. Humans could not have survived.
