Energy certainly can be created: from matter.

I think some old duffer called Albert had an equation to work out just how much energy you could create for a given amount of matter.

The law of conservation of energy states that the total amount of energy in an isolated system remains constant. A consequence of this law is that energy cannot be created nor destroyed. The only thing that can happen with energy in an isolated system is that it can change form, for instance kinetic energy can become thermal energy. Because energy is associated with mass in the Einstein's theory of relativity, the conservation of energy also implies the conservation of mass in isolated systems (that is, the mass of a system cannot change, so long as energy is not permitted to enter or leave the system).

Ok, how about Brittanica:

The first two laws of thermodynamics state, in essence, that energy can be neither created nor destroyed and that the effect of physical and chemical changes is to increase the disorder, or randomness (i.e., entropy), of the universe.

Yes, you are correct. Ignore most of these donkeys as they've not got a clue what they're on with and just bulltulip their way through life.

Are you capable of addressing any question using your own knowledge and experience, or do you have to look everything up using online references?

To be fair, I think he was being ironic (or possibly goldy).

My original answer was from my own knowledge, I was showing you your response was wrong by pointing you to literature.

The average doughnut has more (potential) energy than a stick of dynamite. Burns a bit slower though.
