On the contrary, I believe that the universe is probably teeming with life. Life appeared on this planet pretty much as soon as conditions permitted it, and very quickly expanded to fill every conceivable ecological niche and quite a few inconceivable ones, and I don't see any reason why that couldn't happen on another planet.
What I dispute is that there are technological alien civilisations actually visiting us. First, there is absolutely no evidence of it, blurry photos and vague nonspecific lights notwithstanding. Second, the speed of light isn't just a good idea, it's a fundamental property of the universe and can't be bypassed - if it can, then by necessity everything we know about light and how it works is wrong. And what we know about light and how it works agrees very strongly with what we can measure and quantify. We know we're not wrong.
The nearest star, Proxima Centauri, is approximately four light years away. That means that even light would take four years to get from there to here. Anything that has mass must travel slower than light. Anything that has enough mass to carry a power source, an ion drive, and living crew must take hundreds or thousands of years to traverse that distance.
No. Though I do not know what caused your strange light and probably never will, I am very confident that it was not a technological alien spacecraft visiting us from another planet.
You say you value logic. Can you explain how it is logical to jump from "unknown" to "known to be aliens"?
