Alien Entity Vs. The Nemesis

The nemesis Vs. Alien Entity.
Who wins?(or are they the same being?)

AE.

Probably Nemesis but unsure.

Not the same being.
Nemesis is the remains of the prior universe
alien entity is the embodiment of the spark that created the current universe

alien entity never really fought... While nemesis did...
So in a fight I gotta go with nemesis... Even though he's the leftovers tater than the spark,
