Plenty of evidence has been found. For one, the US government has leaked/released a video showing instant acceleration of a flying object. Nothing on earth can do that.

While it's always good to elevate evidence-based knowledge above "woo" or "belief", it's not healthy to close your mind off completely against anything that isn't currently proven. We might know that we don't know a lot of things, but the most interesting thought experiments happen in the area that concerns the things we don't know that we don't know.

... wouldn't this be a slight smidgen of evidence?
