well barely know one know exept for dead people who lived a billon years ago
year 1991.
1 billion minutes ago was the year 110 . 1 billion minutes later will be the year 3913 .
One billion minutes = ~1,901.3 years.
One billion years is approximately 8,765,810,000,000 hours.
There are 31,540,000,000,000,000 (31 quadrillion, 540 trillion) seconds in 1 billion years.
After plants developed chlorophyll and multiplied to the point where they could "pollute" the primal atmosphere, somewhere between 1 and 2 billion years ago.
1 Gyr is 1 billion years, so 2.8 Gyr is 2.8 billion years ago.
1 Billion years old
it was about 1 billion years ago.
There were no chimps 1 billion years ago. At that time all life was single celled organisms and rudimentary multicellular ones.
No. No multicellular life existed 1 billion years ago. Human-like primates first appeared about 5.6 million years ago and Homo sapiens only appeared about 200,000 years ago.
3 hours = 3 hours PAST 12 o'clock = (3 x 1 billion) - 4.6 billion = 3 billion - 4.6 billion = -1.6 billion years = 1.6 billion years ago6 hours = 6 hours PAST 12 o'clock = -1.6 billion years + (3 x 1 billion) = -1.6 billion + 3 billion = 1.4 billion years ago
There could be no such thing-- there were no people 1 billion years ago.
yes
One billion years ago there were no humans on earth, so 'they' didn't know the distance from the moon to the earth.
Best guess is a proto-bacteria about 3 to 4 billion years ago. First vertebrate was a marine worm about 1 billion years ago.
