Yeah. And when we think we've found the 'first cause' we might later discover that it wasn't the first cause because something caused that!
Or if we find the first cause and fail to find whatever caused that...that doesn't mean nothing did. It may have done and we might find out later, or we might never find out later, or it might simply be impossible to go any deeper and find out later that what we think is the first cause isn't because something actually created that (and it actually might go further and further back down the line so the first cause is much further away).
But if a first cause is found then its assumed to be the 'first cause' until there is any evidence to suggest it isn't and something created that right
I.e science has working hypothesis so after the 'first cause' is found it still needs to keep checking to make sure it hasn't missed something
E.g: That there wasn't a cause before that and that what is thought of as the 'first cause' ISN'T the first cause :p
