This is an estimate based on what we can currently observe, but the number is huge, something like 10 to the power of 25 or even power of 35.
This is so enormous that it is hard to comprehend. Many will not have life at all, let alone intelligent life.
Really, we know so little.
Continuously, I get amazed by the number of planets in the universe. One estimate puts the number of planets as 10,000,000,000,000,000,000,000,000, which is totally mind blowing.
At the same time SETI has been searching the universe since the 1960s and have found not a single sign of intelligent life. To me, I find this odd. In the early days, equipment was not as sophisticated as today. However, by now, I would have expected to find something.
My only conclusion is that our view of the universe must be flawed or that we are somehow missing something important.
To me, all our religious beliefs are too "Earth centred".
I look at the heavens and feel awe.

According to Google there are 10,000,000,000,000,000,000,000,000 planets in the visible universe. This is a huge huge number.
Only some of these planets may have intelligent life, but even if this is just a tiny fraction of the number of planets, this is still a huge number.
I find it mind blowing that I am here at all. One of the greatest puzzles is human consciousness. On Earth we have about 8000,000,000 people. In such a vast universe, you would think kindness and love would have no meaning, yet nearly every human knows this is not the case.
Although we have being trying for about 50 years via project SETI, we have still not found any signs of interstellar intelligent life as far as I am aware.
Most EV and battery manufacturers are trying hard to increase range and reduce costs. We hear today of yet another breakthrough. In my view...
