Decades

The day one of this world when? Decades of decades gone unknown, No counts,no counts, Decades decayed, Still no accounts, This Earth is not just two millenniums, A short count this account, This is the biggest error in the books of account, If this is an error,who and who to account? This world is of millions of millenniums, Decades counted,just bits and pieces of millions, This world is old, The word world also tells it's old, This world is old and old, The old world was in the dark in many folds, Light fell on this world,it's only ten decades old, In this ten,the last decade what came bold, Of decades the last is the first,the best that's like gold!
