Guess what? Even "answersingenesis" says metamorphic rocks were once sedimentary!

http://www.answersingenesis.org/creation/v27/i3/canyon.asp

"Clearly visible in the walls of the Inner Gorge are spectacular light-coloured rocks, such as the pink granites,1 which stand out starkly against the darker, metamorphic rocks2 (figures 1 and 2). The latter are former sedimentary and volcanic layers that have been transformed (metamorphosed) by heat and pressure during intense geologic upheavals in the past."

(Of course, they misrepresent the ages, but that is to be expected...)
