Looking in the Past with Starlight

Looking into the night sky stars is watching a live past, a past in action right now. What we see when we look at the stars is the past, several years, or thousands of years, ago from now. Obviously the reason is the huge distances between stars and us. The light travels those distances in several years, despite the incredible speed of light.

When we look at the horrifyingly huge distances and wide open space, we are looking at how for can not we go. This is a huge wall or obstacle that has to be tackled if we wish to visit a star. And the most terrifying of this is time, the time required to physically travel through this huge space. Tragically, the duration of human life is very short which makes such travels impractical.
So, this makes this earth of ours a big prison which has several interesting things to occupy the short lives of human beings. But outside this earth, there is an unimaginably huge number of extremely interesting big worlds that we humans are wishing to go to, but we cannot, and so we are stuck in the earth.
I don't know what should I call it, but at the time of this writing, there are two stars in partially cloudy night sky. I can see only these two stars which I see every night when I go to sleep outside in summer nights.
A strange kind of feeling I have right now about vastness of the sky and the confinement of the earth, for a few nights. And right now I am looking into the past through my memory and imagination, not through the lights of stars.
