As far as I can tell you have the objection to assumptions that processes that appear to have occurred predictably for going on 14 billion years will continue to do so in future. They might change, but until then I’ll go with the track record.
Oh yes, I agree. If you assume a uniformitarian set of processes for that tiny set of observed data we have recorded, and then extrapolate from that an assumption that they represent ALL processes and then assume that those processes have not changed at all in 14 billion years, then it appears nothing much has changed.
Damn, I bet you set the scale in YOUR logic classes!
