If you do not know how stupid this is then there really is little help for your understanding of science and/or critical reasoning. Among other things a three body system for suns provides a very chaotic system that does not have enough stability in temperatures and other environmental conditions for life to make the kind of progress to get to an advanced state. Take a close look at the evolution of conditions on earth and you can see that there are pretty narrow 'windows' that you have to get through to have the right conditions. Even with a fairly ordered system it took about three billion years to get beyond single cell life.
I am about as certain as can be that there is intelligent life in the universe because the 'experiments' to get things to turn out right have so many chances. Multiple planets in many billions of star systems in a galaxy and in hundreds of billions of galaxies. However, 99.999999999999999% of them are too far away to be contactable. Plus, advanced civilizations have the means to destroy advanced life after not too long so maybe they only last 100,000 or 1,000,000 years, which is a narrow window to match our own narrow window.
