Yes, you are. For example, the Sun is 6 light minutes away (it might be 7 or 8...it has skipped my mind) and, therefore, when we look at the Sun, we are looking at it as it was 6 minutes ago!

When we look into the space, actually we are looking at the light that has reached to us after travelling long long distance. It is representative of the source, but it is not the same. It might have diverted its root and faded to a great extent. In spite of this fact, we can say that we are seeing the thing that had happened long long ago - is true in limited sense.
Even travel within our own galaxy involves time delay of up to hundreds of thousands of years, and actual thing will be much different from what we are seeing. One more thing is that what we are seeing is only visible range for our eyes. There is many things in Ultra Violate region and Many things in Infra Red region that we are not seeing - and it is not known to us - what it is.

That's right and some stars are so far away the light could have left the star while Stonehenge or the Pyramids were being built but the light is just getting to your house tonight. You look up, your eyes catch the light but those stars aren't even located there anymore. I love it!

Absolutely right; and the fact that we are looking so far back in time makes a nonsense of science fiction about travelling to other galaxies, because we are seeing them where they were millions of years ago - so travel to them would be a bit meaningless (and also, they have since moved millions of light years away from where they were). Even travel within our own galaxy involves time delay of up to hundreds of thousands of years.

I don`t think we are looking behind time .just because we are just looking at the stars 10 millio light years away does not mean we are loofing behind time .the lite takes 10 million years to reach us .that`s all
to know more try reading Stephen Hawking`s Books

You could be looking at stars or the person next to you and you are seeing them as they existed in the past.
With people it could be billionths of a second,with stars billions of years but in each case you are looking into the past.

Yes....as light takes some time to travel....if we are looking into space 10 million light years away....we will b looking wat was in tat place 10 million years ago.(as one light year is the distance light can travel in 1 year so the light wud have started at that place 10 million years ago )....
