: ''Main Article: [[Infinite regression]]''

An [[infinite regression]] results when one asserts that a given event caused another, and yet that first event requires another, identical event, to cause ''it.'' The "cyclic universe" model of the origin of the universe is an example of an infinite regression--for what shall we say caused the first among a never-ending series of explosions?

An [[infinite regression]] results when one asserts that a given event caused another, and yet that first event requires another, identical event, to cause ''it.'' [[Panspermia]], an alternative to [[abiogenesis]] as a proposition about the origin of life, suffers from the infinite-regression flaw so long as it fails to state positively what conditions could have brought about an origin of life on a planet other than the earth, ''other than'' the alleged mechanism of the "seeding" of life on the earth itself.
