Faith comes by hearing. In many cases you must hear something to even know what it is. But that is not always true. You could be a man alone living in the jungle and decide for yourself something other than me made all that is outside of me. You could observe that it is well organized, interdependent, and extremely complex. In a natural sense you would be more likely to think that a single power created all. That which surrounds you is so mutually dependent how could it be otherwise? You would not be likely to think that all arouse from nothing millions of years ago.
Today, in these times, outside of the jungle, living with and dependent upon other people, we are told about the “old earth”, billions of years theory - - and we are told about the creator God. We choose between one or the other.
If not informed of an “old earth” you would most likely conclude for yourself there was a creator. The trouble for some people is the creator might tell you, “You can do this but you can not do that.” If you opposed some of those impositions you might shun them and suppose for yourself (and for convenience) a different view: one without the authority. You would invent the “old earth” theory that would require billions of years to evolve that puts the creator conveniently out of sight.
