My question is based on the following information.

"When Astronomers probe the deepest regions of space they are actually
looking back in time. This is simply because of the finite speed of
light. Light moves at the speed of 300,000,000 meters/second (186,000
Miles/second)."

Therefore, with the right telescope and the right position from Earth,
could I view past events on Earth? For example, could I witness myself
as a child? I am currently 26 years old. Would another object likely
obstruct my line of sight?
