What if mutations happens with much more frequency than people imagine, such that it is almost analogous to spontaneous creation sometimes - or actually is spontaneous creation.

Science has a way to factor that in and update its assumptions, but not when everyone dismisses the idea because so much energy has been put into a polar opposite process.
