How about a few Voyager-sized probes with a little decision making ability and some DNA? We aim them at the nearest stars which have at least one planet in the habitable zone. It sounds like something which might be possible soon to me.

What makes you think it sounds possible? Unless you're one of a very small number of people in the world who actually work on this kind of thing, "sounds possible" doesn't mean a whole lot. I don't work on the spacecraft, but I do work on the rovers they carry. Based on my limited expertise as someone in an adjacent field, the ability to send any spacecraft to another star on human timescales is not currently possible in any sense whatsoever. The ability to send a "spacecraft" weighing tens of grams to our nearest neighbor might be possible within my lifetime. The ability to get a voyager-sized probe to another star within my lifetime is as far outside the realm of possibility as anything can be.

Because that's how you get Neon Genesis Evangelion.

(Though I suppose two probes would have to accidentally land on the same planet to lead to that outcome.)
