Considering the trillions of stars in the Universe, how likely would another being find Earth?

Very likely. An alien could hear our radio signals or observe methane and oxygen in our atmosphere. He would then know life was here.
Also, when a civilization branches out into space, they could explore every star in the galaxy in a few million years. That is an instant on the cosmic time scale.

Very slim indeed
Our radio emissions have barely travelled around 100 Light Years
Given the events that have been broadcast over the 20th Century they might even be put off coming at all
Our own Galaxy is over 200 Million Light Years Across
Never mind the 13.4, if it really is, of the Universe
All this is a long way to come
and even finding us would be a needle in a HaystackSource(s): But somebody keeps stealing my sheep !!

The astronauts that were on the moon ,were able to find earth and travel to it.

They could find earth easy enough, but how easy would it be to find you ?

If they can get here, half of their battle is won.
If they have the capability to scan an entire galaxy
and they survey it from above and below, they will
have no problem finding the planets that have water
as a major component of their surface construct and
available from underground sources as well.
It is safe to say that a being from somewhere else
finding the Earth, would be *very* likely,

Earth is emitting a ton of radio waves. With the right equipment it would be simple.

Same way we're using our technology - eliminating the planets we're not all that interested in, and looking for Earth-like worlds...

Assuming their technology is adequate, they can filter down the amount of suitable planets for life.
