The sun is middle aged, it has burned for about 6 billion years and will burn for about 6 billion more years.

Do you think the contributions of these scientists are still valuable,even though some were made hundreds of years ago?Explain your answer.
How many years is the 1.5million light years?
1.5 million light-years is equivalent to the distance that light travels in 1.5 million years.
How many seconds are there in 5000 million years?

How do scientists know that the sun is a million years old?

What type of evidence is these that plant life did not appear until 475 million years ago?
Scientists think that something like this took place in millions of watery environments over millions of years
What event began to occur about 200 million years ago?
Pangaea
When do scientists think that humans first appeared in the geologic time scale?
