If I build a chair, it's only a few seconds old, not even the probable couple hundreds years of the wood that made it. Something/someone is only as old as the amount of time it's/their parts have existed in their current configuration. Light travels infinitely untill something stops it. Like you. Or the ground. The "deprived of reaching the final few feet to the ground" is a stupid and pointless thing to say, because the light isn't trying to reach the ground. Since space is uniform, saying you've never been in the same physical place is bullshit. Technically true, but without an external frame of reference it's completely meaningless. The Galaxy is not named after milk. And it doesn't "take" a whole ocean and a moon to erase footsteps. That's just one of the many and more "dramatic" ways of doing so.
Except that matter can be destroyed. In that it can be converted to energy and as such ceases to exist as matter. Theoretically it could be converted back into matter but it wouldn't be the same matter it was, at best it would just be an exact copy.
Most light that has reaches the earth has already been obstructed in some form simply by passing through our atmosphere.
Footsteps can be erased by rain, waves (which are created by wind), simple over saturation, and a whole host of other things. And shores are not restricted to oceans. Small ponds also have shores and they are barely if at all effected by the moon, but they can still have waves.
I ageee with third.
these posts that keep coming back about how "you'll ever die because matter isn't destroyed" or "you're as old as Jupiter because wagejsndjsjdjsakbs" are just annoying and useless. they serve no purpose other than to just basically have NASA photos under your stupid imitation Jaden Smith captions.
The final frontier.

>look up in the sky
>it's bright because matter has been converted to energy, sent to earth in form of electromagnetic waves
