If going by standard statistics, just our galaxy, the Milky Way, has between 800 billion and 3.2 trillion planets, Earth just being one of these. Then consider the fact there are an estimated 2.1 trillion galaxies, that are the same size as our own Milky Way, many billions of which that are even larger than the Milky Way. The Milky Way is actually fairly low-average to average in size when compared to just the nearby galaxies, never mind the distant ones.
Then you have to think of the Galaxy clusters, meaning how galaxies are grouped into larger "districts" or whatever. I forget the technical term. Anyway, our galaxy, the Milky Way galaxy is part of a Supercluster of 100,000 galaxies called the Lankaea Cluster. Think about it, around 2.1 trillion galaxies confirmed, and our own galaxy is just part of a thick group of them numbering only 100,000 in number. Than another humbling truth is: The Lankaea Supercluster of galaxies is considered a bit of a backwater area in the universe, meaning its sparsely populated, as far as landmasses floating in space go, and then even more humbling is the fact that we are in a very backwater region of the Lankaea Cluster, which is already considered backwater. So, we are in the boonies of the boonies of the boonies.
All of this means that its very likely that the only reason we haven't met other intelligent life, is because we are in the middle of fucking nowhere, as far as space goes. Like, imagine a single itty-bitty housefly living in a jungle the size of the entire continent of South America. Literally, it is the only house fly in existence in the entire continent. We are that housefly, and the continent of South America is the boonies. According to statistics, we are so outrageously in the middle of nowhere and away from ANYTHING of significance, that its possible that our sun poofs and destroys this whole solar system, and it'll still be trillions and trillions and trillions and trillions of years before anything even has the faintest idea that we, or anything at all, ever lived and breathed here.
But aside from all of this, statistically, with between 800 billion and 3.2 trillion planets alone in just our galaxy, the numbers I last read are, there has to be AT THE VERY LEAST, a little over 80+ million planets with life that would again, AT THE VERY LEAST be as intelligent as regular animals like cats, dogs, tigers, wolves, etc. So if nothing else, there are shitloads of planets that are going through their own version of the Pliocene Era, which was the last era in which mammals still dominated the planet but still no form of what is considered a "human ancestor" had arrived yet. So I still get my giant Terror Birds, but I don't have to worry about pesky human-ape-ancestor things
