They don't have to be incredibly advanced in all areas to send a probe here.

We're not far from being able to reach 20-30% of the speed of light with light sails and laser arrays. Say they are 100 years ahead of us in that tech and have figured out how to get to 50% with the ability to slow down before they reach their destination.

If they're in our neighborhood, they could reach us (with a probe) in a human generation or two while not being miles ahead of us technologically.

Good, I don't think I would go well with alien ranch or humus dip.

I feel like food from another planet would induce allergy in many people, and perhaps almost all of their lifeforms produce something that is normal to them but extremely toxic to earth life.

Well, as much as going light-speed would revolutionize space travel, its not "fast enough".

For reference, the closest galaxy is 25,000 light years away, which would take 25,000 years to go to (or come to us) at the speed of light. Assuming of course theres no one except us in the Milky Way, and that there is someone in that galaxy. If someone is even "only" 1 light year away, it would take 1 year to send/recieve a message. Unless they send a spaceship to directly communicate with us that is.
