it is saying its 4.6 billion years old and said later on(thousands,milloins or billoins of years maybe) it will get to hot for life on earth then explode later on (^"ditto"^).but when is too hot and when is explode?

The Sun will not explode. It will, billions of years from now, grow to be a red giant and melt the Earth. The Sun increases it's intensty about 10% every billion years, so in about a billion years it will not be very comfortable on Earth except in extreme Northern or Southern hemispheres

The sun is about 4.5 billion years old, and will last another 4 or 5 billion years (give or take).
At that time, it will have exhausted its hydrogen fuel and will start fusing helium. This produces more heat, and the sun will start to expand into a red giant. The surface will expand out to as far as Venus's orbit (or possibly further) and the additional heat on earth will make life here impossible.

It will probably not explode, but it will expand in a few billion more years, perhaps 2 billion more. It will be a red giant and then contract to a white dwarf.

The sun will become too hot for life on this planet in about a billion years. The explosion you speak of in the case of our sun will be more of an expulsion of the outter layer of the sun. Our sun is not big enough to go nova. This will happen in about 6.5 billion, I think.

It's going to inflate out to about the asteroid belt in about 5 billion years.
You won't have to worry about it though. The milky way is going to crash into andromeda before then, in about 3 billion years.

Thousands, millions, or billions of years maybe...

The bible says the earth is stationary in the center of the universe and that it is only 7k years old. so there you go.
