I enjoy the explanation. I felt as though I was able to grasp what light-years mean.

It mean that if you travel in the speed of light, it take 4.4 years to reach alpha centuri. And you also looking it 4.4 years past ago.

Great presentation, well done & thank you! This is perfect for folks like myself who aren't as familiar with astronomy & astral concepts.
I now understand how light years are measured & how the stars in the night sky are actually reflections of the past.
This was also a very humbling & comforting reminder of just how tiny & insignificant we really are, in the grand scheme of the universe (or multiverse).
