So far we've seen no verifiable evidence of other sentient species. That said, I believe with some certainty that somewhere in our galaxy at some past, present, or future time, a sentient species did/does/will exist.
Why haven't we heard from them?
Perhaps they are not technologically advanced enough to be heard. They may be mastering stone knives right now, or experiencing their own Rennaisance.
Perhaps they are here right now. Any species sufficiently advanced to travel interstellar distances would be able to hide or masquerade with ease. That Boeing 737 that just flew by may be a surveillance craft.
Perhaps they are so far away they will never notice us and vice versa.
Perhaps they existed a million years ago and died out.
Perhaps they will exist a million years from now.
It is really impossible to know for sure.
The Drake Equation suggests that there is sentient life out there. The Fermi Paradox casts doubt. Play around with the calculation form at the second link and see what you think.

We already have.
Although you need rocket fuel to get into space, there are many alternative ways of propulsion....
You could use the ion drive, which spits out atoms, VERY FAST. there is already an ion drive spacecraft called Deep Space 1.
You could also use a solar sail which is also VERY FAST.
Also, if an UFO crashed on earth, we could research how they got so far, to be able to come to Earth, which would be very useful :D

An example of foreign life visiting the earth would be meteorites or solar radiation so you are correct every day there is a visitation but its not unidentified its recognizable

The burden of proof is on you. Show us one concrete physical evidence of alien crafts on earth and not just urban legends and conspiracy theories.

soilent green. that's it. lol
UFO's don't run on fuel. So ask yourself ; What could possibly move an object over unknown distances without respect for gravity & heat, or the absence there-of. possible answer...imagination.
