Dear philosophy stackexchange,
I'm curious as to whether there have been arguments by philosophers for there being a finite past/future or whether it has always been past/future temporally infinite? Ever since i've first been met with the substantialist/relationist discussions in spacetime philosophy and the Kalam cosmological argument by William Lane Craig i've been curious as to whether it even makes sense to say that time ever began. In particular what do relationists or positions close to a near reductive account of time make sense of time having began whether it even makes sense from this perspective.
I'm also wondering about what process philosophy has to say about the finiteness of time given that particular branch of philosophy puts dynamism at the heart of its metaphysics. Thank you for all of your consideration and info.
Sincerely, a freshman college student going on sophomore year
