Allow me to be rather vague by briefly stating the basic assumptions of an hypothesis I posed to myself some 35 years ago (read weed was involved... thus the sketchiness that follows).

Preface :

The study of plate tectonics and the study of stratification of the plates are based on current (recent) measurements.

Extrapolation of each of the above has indicated the earth is, in AV (air value), 6B years old.

Years are define by humans as the passing of a solstice, be it the summer or winter solstice.

Inertia is inertia.

Postulate : The earth's spin is slowing asymtotically as the mass of the plates are distibuted by the interaction of centripetal and gravity forces acting upon all but most importantly for human observation, the outermost components of the earth. Ergo, time, as perceived and recorded by humans as years is and has been in flux.

Justification of proposed investigation/study : May such a postulate explain the recording of seemingly impossible claims by both religions and science as viewed by either?

Corollary proposal : Should we smoke another spliff?
