On a more serious note, I disagree with most opinions I've seen about aliens. The first group believe that any sufficiently advanced civilisation is benevolent and I think that's nonsense. Why should another species that finds us feel the want or need to help us at their risk and cost?
Another group believe they are outright malevolent and dangerous, some believing they are fallen angels or demons... which is ludicrous.
First of all there must be a virtually unlimited number of civilisations given the size of the universe, even in our own local sector of stars we beginning to discover new planets and we're realising that most stars have a planetery system and that after all Sol isn't as special as we previously thought it was.
For myself I believe it depends on whio we meet, they could be pacifists, they could be belligerent, they might have some stupid religious beliefs that forces them to exterminate us because we are infidels, or they might be sentient machines that destroy organic life out of spite.
It's all speculation !
I agree that before seeking contact we should be at least capable to defend our planet and our solar system. Our current level of technology leaves us as unbelievably vulnerable. Any space faring civilisation would destroy us no problem, like shooting fish in a barrel.
Our only defence are nukes and any alien ship should be able to destroy them before they even left the atmosphere. And think about it, they could just deflect massive asteroids at us and completely destroy the planet...
