It's called relativity. A light year is a distance, not a time, about 9.7x10 to the 15 metres, or 1/3 of a parsec.
and it's from the perspective of the photon that time doesn't exist. In other words, relative to the photon, time doesn't exist, but to US, the photon experiences time.
As far as a photon is concerned, it is both at the place it was emitted, and in our eyes at the same time.

You're talking shit. Light isn't timeless, it just travels really, really fast. Faster than the human eye could process.

I'm telling the truth. It is a fundemental truth which has been proved.
Just accept this ( I am a physics student ) and move on.

i heard that scientific research
proved research to be completely unusable, and in fact, to yield results which are precisely the up-side-down versions of the actual truth.
for instance.
did you know, that research has proven that swingsets actually only swing when they are being viewed by someone who is being suspended up-side down above a mostly grassy field with some bare spots of dirt and one small irregularly shaped patch of mud, around which two hundred and fifteen third graders run, for fifteen minutes every other half hour, on monday through friday, but only when two as-yet undiscovered stars are not perfectly in line with minnesota and someone in a south-eastern country taking a hearty gulp from a sparkling red can of coca cola?
