I'm told it's not as difficult to study what has happened compared to what will happen because every event leaves evidence. What scientific evidence exist of the energitics used?

The big bang is the idea that the universe was once (about 14 billion years ago) much smaller and much hotter than it is now, and that it has been expanding and cooling ever since. There is lots and lots and lots of evidence of that--cosmic microwave background, structure formation, nucleosynthesis of light elements, and a lot more.

Science can't do more than speculate on what happened before the first fraction of a second. If you want to claim that god started it all, be my guest. The claim has no observational consequences, so it is more metaphysics than physics.

Alexander may be right--this could explain how the suicide bombers get their 40-virgin paradise after death--they blow themselves into creating a whole new universe.

before the big bang, there was the BIG FIRECRACKER which was apparently smaller than a grain of rice.

inside were teeny tiny particles at least two types, maybe more. The particles repel/attract each other in such a way that they will orbit around each other, and attach to TIME, this is what we call a PHOTON.

Right after the big bang, there was not enough SPACE for photons to form, so the particles took on convoluted orbits around each other, forming what we call MATTER.

Today, when we want to transform matter, we must create very high pressures, similar to the state of the universe before there was room for light. This tremendous pressure is created naturally inside STARS, and that is why they have thermonuclear reactions releasing energy inside them.

So, the "explosive" of the big bang was the natural repulsive forces inside photons.

Nothing was used in the Big Bang, the Bang just happen itself.
The Big Bang is not an explosion of matter moving outward to fill an empty universe. Instead, space itself expands with time and increases the physical distance between two comoving points.

Interestingly, your TV set tuned to no station provides some of the evidence. The "snow" on the screen is in part created by the background energy of the known universe. That energy is what's left some 15 billion years after the BB. By backtracking the existing energy over time, they have been able to determine the source of that energy had to have been a HUGE influx of energy...manifest by extreme temperatures (e.g., 10^27 deg C). [See source.]

Mapping the background noise of the universe supports this because that background energy has some, but not much, variance. These slight variances gave rise to the early protogalaxies, which gave eventual rise to our current galaxies and planets.

There are other physical indications supporting the BBT. The mass density distribution of the known universe suggests a point origin, followed by a fairly, but not entirely, homogeneous expansion. This, too, is consistent with the BB and its atom (string) sized origin.

And, the continuing expansion of the universe suggests an "outward" movement consistent with something that began at a single point. Think of our universe as a big balloon with dots representing galaxies painted on the skin. Our known universe (15 billion light years around us) lies on the surface of that balloon.

The balloon, consisting of the known and unknown universe (the part lying outside 15 billion light years from Earth), continues to expand from its point of origin, the BB. As it expands, the skin stretches and the dots on it get farther apart. This stretching of the universal skin is what Hubble observed when he noticed a red shift in all the galaxies. That is, all our galaxies (on average) are drawing away from each other. Not because they are moving wrt some reference frame, but because space between them is expanding. [See source.]

As to the source of all that energy in the BB, string/M theory offers one WAG: two parallel universes collided and their respecitive changes in momenta released all that energy at the point of collision. [See source.]

(NB: The galaxies are moving on their own, in addition to the spatial expansion. In fact, some galaxies, like our Milky Way and Andromeda, are on collision courses. But overall, the galaxies are getting farther apart because of the universal expansion.)

Before the big bang energy did not exist, the answer is, none.
