Around 70 million years, near the end of the age of the dinosaurs. There are fossils of marsupials 125 million years old, and therapsids (mammal-like reptiles) existed in the Triassic, 200 million years ago.
"Since God made the earth. which would be over 7,000 years"
Go back to The Bible....
Anyway on a realistic note....quick search on Google:
"The massive gene study suggests that modern orders of mammals first evolved when the continents were separating during the Cretaceous era about 100 million years ago--much earlier than some previous estimates based on fossil studies, which link the evolutionary event to mass extinctions 65 million years ago"
Synapsids, which would evolve into mammals, separated from other amniotes about 300 mya (million years ago). True mammals, however, did not begin to appear until between about 250 and 200 mya. Most of the modern mammal orders that we see today did not appear until between 60 and 30 mya.
Mammals have been on Earth for the past 200 million years. They evolved after reptiles and before birds.
In the Cenozoic Era, sometimes known as 'Age of Mammals'
About 65 million years ago.
Day six of creation. Same as you and me.
Earth and Neptune formed together so it has lived the same number of Earth Years as Earth has.

Siberian tigers have lived on earth for around seven thousand years. Surely many hundreds of thousands of years?

about 6,000 years
He lived on earth for about 30 years
2 million years ago
Maximum a human being has lived up to 126 years. UNBELIEVABLE!! but factual.
I think they lived (the dinosaurs) for approximately 165 million years.
Jesus Christ lived for 33 yrs
3.5 to 4 billion years
Dinosaurs - about 150 million years. Humans - about 1 million years.
