Just Because You've Proved Time Doesn't Not Exist, Doesn't Mean It Does

There is much evidence,
That Time really exists,
Through the observation of change through time,
That's not tricky, is it?

The fact that if you take a canister,
Then you fill it with gas,
And the molecules begin all lined up,
They will get pretty mixed up fairly fast,

Somehow shows us that Time is a real thing,
'Cause chances are they won't,
Return to the shape from whence they did start,
And often they just don't,

Yet one believes,
That given etern'ty,
They must return, I guess infinite times,
Which is the real problem of this theory.
