Page "Arguments for eternity" Paragraph 6

Maimonides challenged the inductive assertion on that " everything in existence comes from a substratum ," on that basis that his reliance on induction and analogy is a fundamentally flawed means of explaining unobserved phenomenon.

According to Maimonides, to argue that " because I have never observed something coming into existence without coming from a substratum it cannot occur " is equivalent to arguing that " because I cannot empirically observe eternity it does not exist.
