Just as a thought experiment. Lets be aggressive say 5% of those have evolved beyond bacteria, into something like Plants and Amobea. Down to 5 million, ~ 1 billion years ago
Then you look at the same 5% might have complex animal life, you are down to. a 1/4 million. ~600 million years ago on earth
Then if you look at the same 5% having life that has developed, manufactured tools or clothing or selective breading or agriculture. Something that shows long term thinking, Your down to 12,500. ~18,000 years ago
Then if you look at 5% of that developing writing, something that allows passage of knowledge, science and math, you are down to 650. ~6000 years ago
Is there a chance we are the most developed of 650 planets that have developed Math and Science, maybe, maybe not.
I could see my line of thinking being completely wrong because of Moores Law normally used with computers, but seems work just as well if you look at evolution.

You are assuming we are amongst the most developed. We could very well be extremely primitive and be grouped amongst the middle. There could very well be societies that have existed that are hundreds or thousands of times more advanced. There may even be life that we wouldn't even recognize using our definition of it.
One of the biggest variables in discovering other life is having that other life form exist in the same window of time as us so that we can actually communicate with each other. Thousands, even millions of other intelligent life forms could have existed over the the last 13 billion years, but we have only been able to listen for them for about 75 of those years. And that is assuming they will use radio waves for communication.
These other life forms could very well be extinct now, or have evolved past a physical form, and are now on a plane of existence we are not compatible, or intelligent enough to communicate with. Or their technology could be so different, we haven't yet discovered the method they are using.
