i accept the validity of isotopic dating based on the decay of unstable atoms, so yes i accept the earth is billions of years old.  i do however concede the fact that these decay dates for most isotopes are outside the observable period of time of human beings. if an isotope takes 2,000 theoretical years to decay then it is just a scientific theory that the decay occurred in that way.  the theory may be backed by geological data and tons of great science, but it is still just a theory.  this is the same reason that micro-evolution is entirely proven and macro-evolution is still just a scientific theory. the time scale is too large for us to observe macro-evolution.  still there is almost unlimited data and science backing up the existence of the human soul and i would be glad to break that down for you.
