It is estimated the Milky Way galaxy (ours) has between 100-400 billion stars and probably at least as many planets. It is estimated there are 2 trillion galaxies in the visible universe. That is a huge number of stars! There are about 6-7 billion humans on earth. Intelligent life has existed on Earth for a very tiny fraction of the time life has existed here.
Yet, we are conscious of our existence at this moment on this planet and we would not be here if just one ancestor had done something different.
Truly mind boggling.
