My point was simply that when it comes to origins or anything of the unrecorded past, everything that science can tell us must be taken on some degree of faith
When it comes to anything in this world, everything that anything can tell us must be taken on some degree of faith, starting with the
assumption that there is a world external to ourselves that can be sensed. Every observation we make, even you reading this message, is of the past, and the assumption that our records somehow make those observations more valid is just that ... an assumption. There is no real distinction between "operational" and "origins" science.
