If the law of conversation of energy is right. The energy is neither be created nor distroyed. But how the energy created first at the beginning of the universe. If it was created initially why can't we create it now. And the fact is that we are using the energy in our daily life. And it should the energy is existing and now I am thinking that it not only convert from one form to other but it can be recreated.
There is no definitive answer to this question. We don't exactly know how energy was created in the first place. The Conservation of energy that we were taught in school was incomplete. It works very well for solving problems in classical physics but at quantum level... There is something called Quantum Fluctuation.
A Quantum fluctuation is a temporary change of the amount of energy at a point of space for a very brief period of time as explained by Uncertainty Principle. This allows the creation of particle-antiparticle pairs of virtual particles.
One possibility is that a process called “inflation” could then have rapidly expanded a quantum fluctuation, causing the Universe to come into being. So the Universe might be a quantum fluctuation on an epic scale. This is probably where most physicists currently lean towards.
Another theory is..The singularity that existed before Big Bang could have contained the Universe's energy. It might have originated from a previous universe's big crunch or a black hole.
If you are not satisfied with these answers, you are not alone. Like I said before, There is no definite answer yet.
And.. As of creating energy.. With the current laws of physics... is impossible. Our current laws are accepted because they agree with our observations. If we weren't observing properly and if there is a breakthrough and it proves all our physical laws wrong... Then we may be able to create energy.
As far as I can see, yes. Current science is based on estimates and averages over large tracts of space: Simple Mathematical Proof of Perpetual Motion (https://nathancoppedge.quora.com/Simple-Mathematical-Proof-of-Perpetual-Motion)
