Since the garden of Eden wa created
The planet itself has been itself since it was first created by lots of bits of rock and the force of gravity. But Earth probably got its name when people learnt to talk and s…tarted naming things, and the term "Earth" was applied for that purpose only when the English Language developed. Scientific evidence leads to the conclusion that the Earth has existed for about 4.54 billion years. Christians with a fundemental orientation often conclude that it is about 6000 years old. Other groups will propose other ages. By the way Earth with a capital E is the planet, without a capital e it is the mud soil, and rock.
i don't know how long they have been endangered but if someone knows please answer my question
In their present form, or a least something like it, around the 4,000,000 yrs mark.
The first Chinchillas on earth were discovred in 1100 AD and started up again in the 1400's.
The human species (Homo Sapiens sapiens) started its existence between 110 000 and 50 000 years ago. Its development diverged from the apes about 5 million years ago. The eart…h has been capable of supporting life for about 3 billion years, and is expected to continue being able to support life for about 5 billion years in the future. If we viewed the period of being able to support life as 24 hours, then we are now about 9 o'clock in the morning, humans diverged from the apes about a minute ago and the human species started to exist 1-2 seconds ago. However life on the earth has only existed for about 1% of the time the earth has existed..

In Human Origins
It would very much depend on your point of view and your belief in a deity. Some religions proclaim mankind has been on earth for about 6000 years, others believe different…ly. Scientifically Modern man, Homo Sapiens, is believed to be on the order of 50,000 years old. There were, of course, precursors to the genus. Neanderthals and Cro-magnon for instance. For which there is evidence dating back much longer.
In Endangered, Vulnerable, and Threatened Species
The zebra in general is not endangered tho' some types are heading that way.
