Welcome to the forum.
I'm pretty new here myself. I just want to make some statements.
1.)I'm not the best typist-hang in there.
2.)I am a devout Christian and beleive in Evolution.
3.)Unlike Creationists I look at things objectivly.
4.)Creationism is plain wrong.
And yes, you are correct. A year and a light year are not the same thing. A year is a measure of time. A Lightyear is a measure of distance. So if something is a Light Year away, it will take the light from that star or object a year to reach Earth.
If you see something that is 100,000 Lightyears away, it took 100,000 years for the light to reach us. Currently, the most distant object we've been able to see is slightly over 13 Billion Light years away. That means that the Universe is at least 13 Billion years old.
Now none of this has to do with Carbon Dating which is the subject of this thread so I hope you'll join us in that discussion.
