The Crab Nebula or M1 has a supernova designation of SN1054 (SN=Supernova) and (1054 was the year is was observed).
It is located about 6,500 light years from us, so it would have exploded about 6,500 years ago - give or take a few hundred years.
The Earth did not explode but it had a fairly heavy collision with a planet called Theia about 4.6 billion years ago.
Our Sun did not exist till about five billion years ago.
A long time ago smallpox was deadly, but now there are mandatory vaccines that you get.
No. Crab is very prone to spoilage. Please don't eat it.

You see million years ago there was a HUGE clump of gases which they call "nebulae" well the gases formed together and then came are star the Sun.
It's not the same as a supernova--the Crab Nebula is the visible remnant of a supernova event which occurred about 7,500 years ago. The light from the supernova explosion reached the earth and was observed by Chinese and Arab astronomers about 1,000 years ago. The Crab Nebula was the first object to be identified with a supernova which was actually observed during recorded history.
A very long time ago is how ever long you wish to make it there is no set time for a very long time ago.
