yes
There is evidence for life on earth at least some 3,600 million years ago. So the answer is non of the above but "thousands" of millions of years.

1 million (1000000)
About 2 to 3 years.
A million weeks is 7 million days, /365.25 is 19164.96 years.
Based on a conservative estimation of rotational time around the galaxy, the next "cosmic year" will be in about 110 million years.
The orbit of the sun (a cosmic year) is around 225 million years.
The air 1 million years ago was pretty much the same as it is now.
About 200-250 million earth years. This is known as a Cosmic Year or a Galactic Year,
About once every 200-225 million years. The fancy shmancy term for this is "Cosmic Year".
One million years on the geological time scale represents one million years of Earth's history. It is a unit of time used to measure and discuss long-term geological events and processes.
It is 20 cosmic years old. A cosmic year (for those of you who don't know) is one whole orbit around a Galaxy.
Earth has experienced approximately 225-250 million years of galactic years since it formed around 4.5 billion years ago. A galactic year, also known as a cosmic year or a cosmic calendar year, represents the time it takes for the Sun to orbit once around the center of the Milky Way galaxy.
On the cosmic calendar, which compresses the 13.8 billion-year history of the universe into a single year, one month represents about 1.15 billion years. This means that each day on this calendar corresponds to approximately 37.4 million years. Consequently, one month symbolizes an extensive period in cosmic terms, illustrating the vast timescales involved in the universe's evolution.
They died out around sixtyfive million years ago- but I'd imagine they'd be pretty common before then.
In the cosmic calendar, which compresses the history of the universe into one year, 350 million years ago would fall around early December. This period corresponds to the late Paleozoic era, specifically the time when the first forests were appearing and early amphibians were evolving. It highlights a significant transition in Earth's biological history.
Between 222 million years ago and present, because birds are technically dinosaurs, but traditional dinosaurs died out 65 million years ago.
