Why is life programmed to survive?

[Jenny A]

I have been wondering, why is life designed and programmed to survive? From our genes to our teeth, everything we have is in order to survive. This is also the case for plants, and every living being. We also know how this process happens from a biological perspective. Evolution, etc.

But now the question remains, why does life struggle to survive? This universe, or even Earth, does not care if there is life or not. And actually, chances are every life on Earth will disappear, as it has happened to 99% of all species that have existed. The Sun will eventually grow enough to absorb planet Earth, and then it will explode, making sure nothing will be left. 

I know this may be a philosphical question too, not only a scientific one. But as far as I know this question has not been answered. On the big scheme of things, we does life fight to survive?

All life may or may not have had a will to survive.  But any life form without either a will to reproduce or a will to survive, wouldn't survive long. What you see is those creatures who have survived.  Thus you see creatures with a will to survive.  Next.  . . .
