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.
4 Billion yeas old. 1000 Million = 1 Billion.
The prefix "giga" means 10 to the 9 or 1 billion.
Simple life forms like bacteria have on the Earth for about 3,500,000,000 years ago (3.5 billion years). Evidence of this was found in very old rocks in Australia. The estimated age of the earth is 4.5 billion years so life originated just 1 billion years after the earth formed.
Earth is approx. 4,550,000 millennia old. 1 millennium = 1000 years.
Earth is estimated to be around 4.5 billion years old. The earliest signs of life on Earth date back to approximately 3.5 billion years ago, suggesting there was around 1 billion years between Earth's formation and the emergence of life.
1 Billion years old
it is 1 billion years old
4 Billion yeas old. 1000 Million = 1 Billion.
1 billion years old haha :)
Most stars get about 1-10 billion years old.
labradorite is roughly 1 billion years old.
There could be no such thing-- there were no people 1 billion years ago.
about 1 billion years old
The Earth is about 4.5 billion years old. Life appeared on Earth about 3.5 billion years ago. The Earth would have been about 1 billion years old at that time.
To determine how many years old you are if you've lived 1 billion seconds, you can divide 1 billion by the number of seconds in a year. There are approximately 31,536,000 seconds in a year (60 seconds x 60 minutes x 24 hours x 365 days). Dividing 1 billion by 31,536,000 gives you about 31.7 years. So, you would be roughly 31 years old.
approximately 1901He is 1,901.34 years old.1,000,000,000 minutes is 1,901.3 years.
1 billion years = 365.25 billion days (rounded)
