Yea because we ate and murdered everything that was slightly intelligent. They're all extinct. LOL. There may have been a more intelligent species but it didn't breed like rabbits so up popped us.To date, we have explored less than five percent of the ocean.
We don't even know our own planet and yet people think they know there is no other life in the universe? How ignorant.
I've never said there is no other life in the universe. I believe intelligent life, as we know it, is extremely rare, if it exists at all. I base my belief on what we know of life here... which is still the only life we know of.
Consider the billions of life forms here and the billions more that have been here. Yet humans are the ONLY life form to have achieved technological advancement. Consider, if not for circumstantial events which randomly happened, humans simply wouldn't have evolved. We're the products of extreme luck and circumstance.
Are there planets out there with oceans teaming with 7-foot peculiar worms? Perhaps.... but they're probably not building space ships and visiting Earth.
Based on the tiny amount of evidence you have, if I were you I'd admit there isn't enough evidence yet to decide.
I agree probably only 1 in 100,000 stars have intelligent life. The rest have worms and microbes.
