Aaaaaaaargh. There's evidence to support many theories besides the orthodox one ... like that >100Ka site in SoCal ....
J Harlen Bretz's Missoula-floods theory was a 'fringe-theory', until decades later. Alfred-Wegener's plate-tectonics theory was 'fringe' for decades. The Antikythera Mechanism was an out-of-place-object until history found a place for it. Gobekli Tepe pre-dates the pyramids by thousands of years.
Science is not religion, and defending against heresy is a job for dogmatism.
And too often, the phrase "There’s little evidence..." means "I refuse to look at it". One more example: Too bad Milutin Milanković had already died before he was vindicated.
Rinse and repeat for the dogmatists, haters, jealous.
