The Impossibility of an Infinite Past

This modified version of Hilbert's Hotel preserves the essence of Craig's claims about the impossibility of an infinite past. It escapes common objections to it by focusing on the impossible effects of the past rather than the past itself being impossible. Another way to improve Craig's argument would be to say that if the past were infinite, then it could be possible for there to be an infinitely long causal chain. The philosophers like Rob Coons and Alex Press have shown that causal chains cannot be infinite.
