I didn’t say spears didn’t win against swords.
Spears are easier to wield, it’s a pointy stick. It requires less training to use. Requires significantly less materials to make.
They are a standoff weapon though, in close combat a sword or small bladed weapon wins. Different tools for different purposes.
The information I’m parroting is from experts and historians and literature and everything I’ve read over my 4 decades, it’s common knowledge at this point and not really worth “arguing” imo.
Your sacred source might as well be what I just said.
