Maybe we are seeing light that hasn't reached us yet. Why does light
have to reach us for us to see it? Couldn't we see it on it's
approach?

Homeschooling just isn't working, is it.
Seriously, we really need to bring in some checks and balances.
Here is a basic introduction
http://www.preventblindness.org/vlc/how_we_see.htm
Light reflected from an object passes through the cornea of the eye, moves through the lens which focuses it, and then reaches the retina at the very back where it meets with a thin layer of color-sensitive cells called the rods and cones.
Epic phailure at science.
We see light precisely because it has reached our retinas. So, no we can't see light that hasn't reached us yet.
I can hear sound coming.
Hey, look, my inbox shows somebody is about to send me an e-mail.
I'm doing this all from a laptop that's being shipped to me.
I was gonna say, 'Aaaw that's so cute' but this person is probably some well respected 'doctor' or something in their own little community. They probably let out this little gem at some meeting of their community's greatest minds and got a huge gasp of impressed amazement from the crowd of bad haircut wearing victims of society sitting around the table.
This is one of simplest, most concise examples of scientific ignorance I have ever seen. What this makes me wonder is - is it the lack of scientific understanding that allows these people to persist in their religious beliefs, or do the religious beliefs inhibit their ability or motivation for acquiring scientific knowledge? My guess is both.
No light, no sight.
No brain, no pain.
{sweatdrop} Scienceman123 SUBMITTED it; he didn't craft it.
Annonymous apparently doesn't realize we don't see objects per se, but rather the light reflecting off of them...
Only if you have super-powered, ultra Jesus eyes that can "see" light without actually seeing light, because it exists beyond your puny mortal limitations of space and time. And all you heathens that disagree with my ability to see the unseen will burn in hell for your blasphemy!
Someone, please tell me he is not allowed to vote or breed, for gods sake, the inhumanity of such ignorance.
I'd normally just assume he doesn't know how sight works, possibly because he's never had an opportunity to learn...
... but calling himself 'scienceman' dispels any sort of sympathy I might've had.

Electromagnetic radiation travels at approximately 186,000 miles a second in a vacuum.
Next stupid question...
Meh, to be fair, if you don't know that to see light, a photon from the source of light has to stimulate a photoreceptor cell in your eye, that's not really your fault and I can imagine thinking that it would be possible to see light "coming", so to speak. Apparently around 50% of American college students believe in the obsolete "emission theory of light", which says that you see things because your vision is somehow "coming out" of your eyes: http://www.ncbi.nlm.nih.gov/pubmed/12094435?dopt=Abstract
Now THAT is dumb.

No. If the light hasn't reached you, it hasn't reached you.
Your eyes are essentially photon detectors. Light is made of photons. If those photons don't reach your eyes, then your eyes don't detect them.
Your eyes can't somehow reach out to "grab" the photons en route (Cassiterides, I'm looking at you here. Please take note).
What you're asking is, couldn't we see something before we see it?
The answer should be fucking obvious, even to that brain-dead life form called a fundie.
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
