One should also mention the anthropic principle in connection with this: the reason we haven't drawn a black ball is because we're here to observe that we still exist. Also of interest is the Fermi paradox: if (relatively high) estimates for the prevalence of extraterrestrial intelligence are correct, why haven't we found anyone? Taken together, it seems very likely that there is in fact a black ball in that urn, and we just happen to be one of the extraordinarily lucky planets that has not yet found it. Oddly, this is kinda freeing in a nihilistic way. If you know that you and your species are going to die eventually (which you do, the eventual fate of the universe is heat death), you can focus on living for the present instead of brooding on the inevitable death of mankind, and just be grateful that you and your species happen to be alive at this particular time on this particular planet where life is actually a thing.
