AGNOSTICISM is about your HONEST perceptions and interpretations of your own experiences. If you cannot see beyond the horizon, you don’t pretend you do. Of course, you can gather information from credible sources who have seen something beyond YOUR horizon, but that is tentative information that could be a basis for your belief(s). No one credible to me has ANY information about Earth’s origins. We can only theorize based on patterns of evidence from various credible sources. Beyond that ... If you are not agnostic, you are playing a make believe game. If so, you have faith in fantasy instead of reality, in my opinion.
