I really hope you don't think humans have existed for only 2,000 years.
That's a good point. At first glance I thought it was correct... O.O In fact until you said that I thought it was correct.
I blame myself, for not paying attention at school... :P
Uhhh what do you mean "if it's true" i'm pretty sure scientist have pretty much proven that the earth is billions of years old
Sorry to interrupt, but it's we humans, not us humans. You are now free to continue your historical debate.
Of course not, I'm just saying since the first A.D., we've been technologically globalizing everything very, very rapidly to the point to where we're modernized and settled. Compare that to before, and it shocking.
How did humans screw up I don't understand. I'm pretty sure humans are doing a damn good job creating everything from nothing.
Universe 14 billion years
Earth 4.6 billion years
Life 3.5 billion years
Humans 200,000 years
We're actually studying this in my history class~
Homo erectus have been around for about 750,000 years. Homo sapiens sapiens [why they have it twice is beyond me] have only been around for 200,000 years, though.
The first development of humans was around 2 million years ago.
When I said humans, I was talking about our exact species. Although the hominids leading up to us were certainly more intelligent then mere animals, it's tough to tell if they were actually sentient. Either way, the time that we've been around for would be 11:59:59 pm if the existance of the Earth were a clock.
It's so interesting to think that.
It seems like 200,000 years is such a long time, but it's not compared to the earth.
Yeah and we spent about 140,000 years of that just sitting around in Africa. And it's only been about 150 years since the industrial revolution. It seems to us that we've been around forever and are going to be around forever, but if we were to go extinct, we would actually be a short lived species compared to most.
So what the hell have we been doing for the past 198,000 years, then?
NOT THE GRAMMAR NAZI!!!
Sorry, it's my calling.
It is rather sad to think how just in 2000 years we have made earth nothing like is was before. It will probably never be the same again =(.
We need a new plague...
I just have to point this out.
It should be WE humans. not us.
The earth is not billions of years old, it's 6000 years old.
what is this i don't even
Science is all wrong. If you go on YouTube, you can see many different videos such as proving how carbon dating doesn't work.
