10 million years since our first ancestors and about 250 thousand years for man as you know. 1000 years since we have started to eat our planet to waste.
Planet Earth has existed about as long as the Solar System - something like 4.6 billion years. For the future, it is harder to know how long it will last. In a few hundred million years, it is expected to get too hot for life to exist on planet Earth, but the planet will continue existing. In 4 or 5 billion years, Earth will ultimately be swallowed up by the expanding Sun.
We don't know. We can go back to within nanoseconds of the Big Bang, around 14.6 billion years ago, but that event makes it impossible to go further. It may be that time only began then - which is why we can't back further, because there is nothing to go to - or it may be that time does go back well beyond that. Whether to only a couple of weeks, or another 20 trillion years, or for an infinite time, is up to what you think.Or possibly a loop in time,Where future and past come together.
Watch BBC's Merlin and you'll have your answer... But more seriously, Arthur probably never existed so we'll never know.
Nature does not 'know' anything. It is not a sentient being.
At the time, there was no humanity when Earth was made. When there was humanity, there was no religion. They had no such idea that God existed. We still also don't know that does really God exists or not.

True humans have existed for 60,000 to 80,000 years. People who appeared fully human (but without all human behaviors) have been around for at least 200,000 years. Before that almost humans have here for about 500,000 years.
None that I know of. There are few. Why do you ask?
We don't know and we never will. Bread has existed for thousands and thousands of years, before countries even existed, while mankind survived in tribes, before books and writing existed. Therefore, sadly, we will never know.
As far as I know, Arabia hasn't existed as a nation for hundreds of years.
It' very hard to tell. You could see something you would call human 200 000 years ago, but humans as you know them today probably originated 50 000 years ago.
She doesnt,she already was she never existed, but she was reborn coz she is technically human. watch the movie and youll know about it.
i know it was a human being
HIV/AIDS. In fact, back then we didn't even know it existed.
It is impossible for any human being to know if another human being is truly happy.
