Solipsism has the fewest entities (only my mind) and therefore it is the most minimal explanation.

Does that make it more likely than the existence of other minds? Because other minds offer billions of minds.

Many entities. Everything in the universe tends to the lowest energy level.

So, should we consider the explanations that have the least number of entities to be true?

Does explanatory power matter more? Is the number of entities crucial or important? What are the solutions to this problem?

Please explain.
