Big Bang theory, in other words, is as good as saying that the universe created itself out of nothing, which is not only impossible but ridiculous.
The reality of life which is most difficult to accept - is all types of pain, suffering and sorrow of all living things. All the evil in the world, would become defunct & obsolete in a hypothetical situation when the above cease to exist. Thus, we can safely conclude that evil, injustice and inequality owes its colossal power to its infliction of pain, causation of suffering and perpetuation of sorrow upon all living things. Evil eternally feeds upon it.
In the hypothetical moment when all of these disappear, evil will disappear too and maybe, also the creation itself. Hence, we can also say that all living things are imperfect for, they can be harmed. No one and nothing is invincible. The creation and its living things, were not intended to be perfect because, the moment the possibility of pain, suffering and sorrow steps in, evil steps in too and only leads to the play of the opposites i.e, Good Vs. Evil eternally, in all their forms and manifestations.
If at all we have a Creator; it would have to be one who is the original and without a cause as the endless process and questions about causation would stretch unto infinity.
God has created us and has thus, seemingly done a great injustice to all of us by putting us all through this. But when we go deeper, we realize that He has also given us His power by creating us as pure potentials, having a potential for evolution and expression of more power and freedom. Yeah, this does not change anything or lessen the pain we have to go through; it is merely a philosophical discussion, to be frank. Every life is seeking more life. Everything is evolving. Everything is in a state of movement, constant flux. Everything wants to express life. Every plant and animal is journeying to become more conscious. Nothing is dead, its a thriving and throbbing universe.
No matter how much pain, enormous endless and torturous; some people may seem to go throughout their lives, the basic structure of cosmos cannot be unjust as it would collapse. Theoretically, every positive has to be balance by every negative and vice-versa. It is just that many a times, lot of negativity is allowed to prevail for a considerably long period of time. Inconceivable evil comes into existence, challenging every goodness.
It is created by humans, not the Creator. It is because the Creator gave the choice of free will, we intuitively and emotionally feel inclined to blame & abuse God for such an abuse of free will, on the part of, those directly responsible for the human condition. Such blasphemy is the natural discharge of emotion and hurt.
Even when people know who are the masters that have enslaved them, nothing much is done due to the power of evil that is spread, far and wide. In such a case, the person does not have much choice but to turn his back to God and also, the entire scientific evolution drama. This he does by abusing God many times in his mind.
All this is caused by the huge amount of negativity in the world and in the person's own life. His own evolution is stalled, and a spiritual person with a good intellect to understand the creation and evolution process, gradually becomes a skeptic. We all are desperately seeking positivity, desperately seeking justice and desperately want the balance restored.
Every wrong ought to be punished with the same momentum & intensity - with the same amount of harm (pain, suffering and sorrow) inflicted, otherwise our Creator cannot be called a 'Just God.' Example - a person directly responsible for killing 100 people without any valid justification, to neutralize some or all of the evil committed must bear the same amount of harm undergone by those 100 people, collectively. In hell or some other realm, where it happens does not matter - the only thing that matters is that it happens. Every evil, punished. Every injustice, brought to justice. Every wrong, repaid. No more, no less.
