The so-called 'scientific' evidence for an old earth is based on uniformitarian stratigraphy, radiometric geochronology, and a self-avowed bias against the Bible...
The evidence is more than "so-called." It is something that people of all faiths or no faith can observe--anyone can observe it but bible literalists. They have chosen to deliberately ignore that evidence.
And the bible is not inerrant. Young earth and the global flood about 4,350 years are two biblical claims that have been completely disproved--to all but biblical literalists.
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
