Are some UFO sightings the solution to the Fermi paradox and if so why, conspiracy theories aside don’t they make open contact?
I’d think, but I don’t know, that the effect of our atomic weapons anywhere else in the universe would be minimal at best. The worst we could do would be to trigger another extinction event on Earth which some claim we are doing already.
The dinosaur killer is estimated to be the equivalent of 10bn Hiroshimas, A technology not too far in advance of us could push one of these into the path of the Earth’s orbit, why would nukes trouble them?
The universe is vast and full of things like suns, novae, FRBs, GRBs; black holes, etc that make our nuclear capability look puny. I doubt that our current crop of instruments could even detect a nuclear war in the system of the nearest star to the sun.
We tend to overstate our progress in getting into space, without denying the achievement all we’ve done is get to the moon and launch a set of probes two of which have reached the boundary of our Solar System after half a century or so.
I’m lucky enough to live near a scale model of our Solar system. I’ve been interested in astronomy since I was a kid and even then I find it hard to comprehend the scale – and don’t forget this is two dimensional not three dimensional! Couple of links here:

It could be the effect of what we are doing isn’t anything we are currently aware of - similar to the Babylon 5 scenario where the Humans are losing a war to the Minbari when the Minbari surrender because they’ve found that humans and Minbari “share souls”.
Or
It could be that they’ve invested millennia tinkering with primate DNA and we’re about to destroy all the work.
Or
A moral dilemma in that they know that contact with a more advanced race would be disastrous for us. However they see us about to destroy ourselves. Do they intervene or not?
As
@eburacum points out we don’t have enough data, which is true of most Fortean phenomena so we’re just guessing; but that’s half the fun innit?
