Strong anthropic principle (SAP): The Universe must have those properties which allow life to develop within it at some stage in its history. The world and universe are not very probable, but it is the way it is because there is a selection effect. Weak anthropic principle (WAP): The observed values of all physical and cosmological quantities are not equally probable but they take on values restricted by the requirement that there exist sites where carbon-based life can evolve and by the requirements that the Universe be old enough for it to have already done so. In relationship with the existence of life this phenomenon relates to the anthropic principle. We see the unlikely event because without it we wouldn't have lived to see the absence of the event.
(and as Mehmet mentions in the comments, this could be seen as a cherry picking fallacy) The fact that we observe the unlikely event of a universe, solar system and planet that is able generate intelligent life, is a type of survival bias. Is that a known fallacy in the formal stats world? If so, does it have a name? In this kind of fallacy we assume that a certain state in a sample space should have a high probability to be random because it's arbitrarily labeled as "special", but, in any continuous distribution, by definition, all possible states would have a probability equals 0. Suppose I threw randomly a dart in a circle and it hit exactly at the point (3, 4), if one says for me: "There infinity many points you could hit, so, if you threw it randomly, the probability (using the limit definition) of you hitting that point is 0, therefore you didn't throw it randomly and must have something external being that rationally made this dart hit (3,4)". But is not hard to notice that it's a statistical fallacy exactly like that one:

It's such a common argument when someone tries to argue the necessity of a rational and active agent creator for the universe that it we see it in an Sheldon's series episode.
"Given the infinite amount of possible configuration of the universe and the fact that if something in the universe were slightly different, we wouldn't exist, we can conclude that it couldn't (or probably could not) be created by the randomness".
