Are We Alone?

[Enlyten]

The reason this is a weird topic is because we ourselves implanted the thought of aliens in our heads; we made it all up ourselves.

Yes, the term; "Aliens" is our own doing. Nothing more.

But its safe to say that somewhere out there is another solar system like ours that has a planet sutable for life like ours. And as I said, its probably just like us. Other humans.
Why not right?

You would be surprised how smart the Mayans, the Greeks, and the Egyptians were. Besides, since the ancient Egyptians and Greeks were very closely related in intellectual societies, I wouldn't be surprised if the Greeks had a hand in building those pyramids. Ancient Greece had a thing for geometry. Personally, I think you're underestimating their intelligence which is quite bogus.

Okay, fine. The mayans, greeks ect were smart. I know that. Some of the greatest scientific minds I know...

The fact that the structures are perfectly designed in terms of angles and measurments is not the issue.
What kinds of technology did they have back then?
Did they have power tools? No.
The egyptians didnt have any tools other then primative hammers and chisls.

There are two factors in this. THe first is the knowledge or science behind it. They arent stupid, your right.
But the other factor is the muscle behind it. How did they shape each BIG block in the shape or a perfect square ect with only basic hammers ect. Even more interesting, how did they stack these enormous blocks without a crane?


What about the Aztecs or other cultures?
There are many other interesting structures of even greater complexity. It just doesnt seem possible given the tools they had availible to them at that time.

Technically "alien" is a name for any race that is not in the current set of population; I would be an alien in terms of the american people.

Also, it would take a while to build a pyramid? No duh, it DID take a while to build the pyramids. Probably took 10-20 years a structure. It's also possible they killed anyone who failed to make a perfectly proportioned stone slab, so... industrial relation laws stopped that happening now.

Sand and and metal saws, no matter what kind (I think they used copper) can easily cut almost perfect blocks out of limestone and to an extent granite, there's probably some demonstration videos online if you care to look for them. I can't remember the mechanism by which it works, but we all know that small particles can cause scratches, never wondered why for example your cellphone gets scratched even when there seems to be nothing harder than what it's made of in your pockets?

And they didn't use cranes, think long cylindrical pieces of wood as wheels and 20 or so slaves pulling one block. There's probably quite a few videos recreating or demonstrating how this was probably done online. And with a bit of sand, it's easy to made a slope to transport the blocks over (though I think other methods are being considered by historians as well). Remember, they had a lot of time, a lot of sand and a lot of slaves. Nothing mysterious about that.

Can you explain me your definition of ''human life'' please?

My apologies, that was unclear. What I meant was life that functions and has a civilized, working society, if not simple life-forms that just... live.

^this @ shadoworganoid

You would be surprised how easily they used their limited resources to make their civilization. I actually read somewhere that a good example of a roller bearing is what the Egyptians did to transport those blocks of stone. They were smart, and if they had their mind set to anything they would do it. Building a pyramid like that is honestly not going to take that much, just a lot of time and effort.

So I am feeling lazy as it's late on a Saturday night... Well not late, but still.. I apologize if I state what others have already.

Here is how I view the situation- Do I think Alien life exists? I think it's possible. Do I think alien life has ever existed? I think it's extremely likely.

Here is why... The universe is estimated at around 15 billion years old, now in that time so much could have and did happen, let's not forget that in the past few million years alone on earth, there has been mass extinctions. Earth has come close to complete destruction before and one must assume that other planets have gone through these same incidents.

The fact is the existence of mankind plotted onto a scale of how old the universe is, is TINY and the time we have been technologically advanced is a speck in time. So to put it into perspective it's like taking a bundle of hay and throwing a needle in, looking for 2 minutes and then trying to deduct a conclusion on whether or not there is a needle in it. We have only just started looking in a huge bundle of hay.

I am almost certain there have been alien species on planets which existed and then died out, quite a few times too- before we began looking- even before we were making fires.

Now you also have to take into account the size of space, it's unbelievably huge and there is SO much we haven't even seen yet, and by the time we do find them another race could have probably existed and died already- let's remember that time is relative and other planets don't have the same existence of time as earth does.

To keep it simple I attached a graph I made of the chances of interaction between aliens and humans alone, nevermind the 1/10000000000 shot of actually looking in the right place. (Those lines of alien existence are generous too).

And when I say alien I don't mean green men with brains in helmets, I mean any life. As that's the definition.
