Someone please correct me, because with a planet that is at 111 light years away aren't we technically looking back in time?

Any type of observation was only a period Of time and any type of life used to be there, but may not be there presently?

Everything you look at is looking back in time.

110 years in the past is insignificant relative to a planet's geological period's age.
