It's not impossible for a whale and a pot of petunias to appear. It is however extremely not probable.
Really, make the universe as big as you like. Make time as long as you like. There is a limit on what will and will not happen. We prefer to use evidence and observations for this. Speculation does not help one bit to change our understanding.
A spontaneous pot of petunias is about the same probability (within an acceptable margin of error) as life appearing (in the vastness of the universe multiple times). So, if we state that one can happen, we have to admit we also believe the other is likely. Are we happy to make that conclusion?
