The Fermi paradox rests upon Drake’s equation. Drake’s equation reads: N = (N*) (fp) (ne) (fl) (fi) (fc) (fL) fl is the percent of life supporting planets on which life develops. This value is obviously not zero, but beyond that we don’t know what the value is. Fermi paradox adherents hold that fl is a relatively large. There is no support for a high fl. In fact, work in abiogenesis suggests that the development of life is highly unlikely. Regardless, there’s no way to currently know the correct value of fl at this time. The same is true of other values in Drake’s equation. fi is the percent of life bearing planets that develop intelligent life and ne is the percent of potential life bearing planets per star with planets. These values are still obviously non-zero, but beyond that it is a total guess as to what the values actually are. The consequences of all these unknowns is that any end value determined via the equation can’t be verified. The Fermi paradox is only a paradox if those presently unknowable values are sufficiently high, but there’s no proof that those values are high at all. You might as well read the entrails of a bird, it would have just as much validity as picking out high numbers for Drake’s equation out of the ether to create a paradox where one may not exist. The fact that we do not see any other extraterrestrial civilizations strongly suggests that the values for Drake’s equation are not high at all and therefore the Fermi paradox doesn't exist. The Great Filter hypothesis is an attempt to reconcile the Fermi paradox with Drake’s equation by theorizing that there is some sort of near universal mechanism that reduces the number the intelligent civilizations in the galaxy. The hypothesis is unnecessary if the Fermi paradox doesn’t exist because Drake’s equation values are sufficiently low. Furthermore, the likelihood that any particular experience is (nearly) universal reduces as other variables enter the equation. It would be hard to imagine a more disparate environment then planets alien to each other and their species. Therefore it seems unlikely that there is some universal experience would be shared across nearly every form of life on every planet on which it arises.
