Finding us wouldn't be a problem IMO, we have been broadcasting our presence for over a century now.

It is possible that they did not detect life forms, just a planet with similar conditions to their own, so they wanted to take a closer look.

I would hope that they would have sent a probe first to gather climate, gas composition etc. but I think it all depends upon how and if they would be able to communicate with such a device, which might be a reason for sending a “manned” mission. Even if they would get to a point where AI is a way of life they might have a combination of AI and beings on a mission together, not just AI by itself.

The question is would these other life forms live in the same atmosphere and similar conditions to us? I think there might be at least one.
Are these life forms more advanced than us? They may be, and if they are and have similar living conditions, they may be looking for a planet similar to theirs which would be ours.
If they did find our world amongst the many, many others, how long would a signal they sent take to reach us? Would we be able to receive this signal, perhaps there technology is different and there signal would not be able to be picked up by our equipment. When we are looking for signals, we are assuming that they would have developed along a similar technological path as us and therefore at one time had the same signals being used as we have, but it is possible that we are wrong.
Before sending a craft full of their life forms, wouldn’t they send a probe first to identify this planet to see if their was indeed life here, but how long would it take their probe to reach us, is it possible that by the time it got here there might have been so much time that they may have even forgotten about it, even if it has FTL travel speeds, unless they have some kind of instant long range communications, wouldn’t it take some time to get their signals returned to them by the device?
How long would it take for the craft to get here? Even if they had a fast way of traveling depending on where they are coming from, it still could take generations to get here.
Let’s say that the planet had made advancements since they left and that their return was eagerly awaited, they would have to go over the research before sending any more “manned” missions.
Even if their first craft came here when we were cave men, by the time their next craft came, we could have been well into the Renaissance age here on earth.
If they were able to move fast for them through space (a couple years at most to people aboard the craft), the two worlds they would be going between would be advancing at their normal rate which would seem an accelerated rate to the people on the craft. Thus between appearances on earth, there would be large gaps.
Though this theory does allow for aliens to visit earth, it far limits how many true sightings that might be viewed.
I am basing this off of how we on earth would more than likely proceed if we found a viable planet like earth to study.
