just the energy requiered to travel to proxima centauri boggles the mind.

Here's somebody who doesn't understand even basic physics. So let's review.
(1) AN OBJECT IN MOTION CONTINUES IN MOTION UNTIL ACTED UPON BY AN OUTSIDE FORCE. This has been known since Newton. That's why even objects that have no power source at all, such as meteors and comets, can travel indefinitely until they run into another object. That's also why probes that we've sent out to view planets in our solar system just keep on flying away from us and out of the solar system altogether.
(2) Einsteinian time dilation tells us that the faster somebody moves the more time slows down for them. So somebody doesn't need a lifespan of hundreds of thousands of years to travel vast distances if they can get close to the speed of light.
So even with our simple understanding of physics and space/time there is nothing the prevents aliens from getting here. And that's to say nothing about what we don't yet know.

I find ant farms fascinating. I love observing them go about their business, but I've never introduced myself to them.
