There are such things as stupid questions. Light is the byproduct of a chemical reaction for crying out loud.
Does light last forever?
Check out the life cycle of a star.
We see stars as they were billions of years ago by gathering far spread out and far travel light photons?
I don't understand. This is also a stupid question, that is phrased in such a way that it has no answer.
If so is there a point were the photon would break down and disipate? DOes light go on for eternity albiet scattered so far apart that it is not
PS This thread is pointless.

There's no such thing as a stupid question. If you don't ask questions, you never learn.
Light is not the byproduct of chemical reactions. Light is the result of a change in energy state of an electrically charged particle. It's what
propagates the EM force. Chemical reactions are not required for this to occur.
The life cycle of a star has nothing to do with whether a photon can exist forever or not.
The second question does have an answer: Yes. That's how a telescope works. It gathers light over a larger area than the eye covers, and focuses
it, increasing the inbound flux to the eye or film or CCD.
