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. | 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.''
