I mostly believe in God because it seems more probable to me than the "Big Bang" theory. As a Muslim, I believe it's my responsibility to know what other people believe in. I have looked in Judaism, Christianity and Hinduism, and now it's my turn to look at Atheism. My question is, in Atheism, What happened before the big bang? What made the first physical matter? What made energy? light? fire?
Thank you.
Atheism is a philosophical point of view, it doesn't involve or require a physical explenation as to what "came before the Big Bang" or things like that. Atheism in not a specific world outlook, but is a category of world outlooks, which have in common that they don't acknowledge that there is a deity.
Most of your question, in sofar they relate to your physical questions, are answered in physical theories, such as the Big Bang theory (it perfectly explains why and from what instant in time there is baryonic matter and why there are photons which we can see in the form of the CMBR, these photons were already there but in this dense "soup" of matter, could not go anywhere and bumped directly into particles, only after atoms were formed, photons became visible light, which we can still detect, in fact it is the olders remnant of the big bang) and as to what was the direct cause of the "Big Bang" this question is answered best by the theory of cosmological inflation, which explains that there was a very rapid expansion of space as the potential field (called the "inflaton" field) slowly rolled down to the minimum of the potential, where it oscilated and reheated the universe, thus releasing the energy which created all the baryonic matter and photons, etc.
For your information, as I guess you want to ask the really profound question as to why at all is there matter/energy, space/time, etc., if you want that asked by physics, that is the wrong question to ask, because any question that physics can try to explain, involves a material state of the universe (which already involves some form of matter/energy, space and time).
So you can in physics ask, why does state X of the universe occur, rather then Y, but you can't ask why is there any state at all. If there isn't a physical state, then physics can not deal with it.
So, if I translate your question into the metaphysical question as to why is there being instead of non-being (and for which you think, your deity provides an answer) the answer is that this question already assume something, namely the absolute seperatedness of being and non-being, which makes it impossible to answer the question.
Since, as we can conclude, being and non-being are in fact not absolutely seperate, but just opposites of each other, which necessarily
belong to each other. They are like two sided of the same coin, or two poles of a magnet, you can not separate them.
You can slice the coin, but then you end up have two (half) coins, each with a top and bottom side. Cut a magnet, and you don't have a north pole and south pole, but two magnets, each with a north and south pole.
[ for clarity, we neglect the weird case which is claimed by particle phyiscs about monopoles ]
The way we can see this is to reflect on them in their higher unity (the dialectical unity of being and non-being) which is Becoming.
Every process that goes everywhere and on all moments in time, involve becoming, in which one thing changes or transforms into another thing, which therefore means: the being of one thing, changes into non-being (ceasing-to-be), and the non-being of another thing, changes into being (becoming).
Example: burning H
2 gas with O
2, which creates H
2O and heat. In this process the H
2 and O
2 become inexistent, and at the same time it makes water and heat.
But you can't make water and heat without H
2 and O
2 (or other chemical components), nor can you get rid of H
2 and O
2 without creating something else. This in general means you can only transform something from one state into another, wether that requires motion, chemical processes, or physical processes. And as far as science is concerned we have always a material state changing into a different material state.
A philosophy or idea which clings on the absolute
seperatedness of being and non-being (which in other words, doesn't reflect on them in their unity, in the form of becoming or ceasing to be) is not called dialectics but sophistry.
I hope this answers your question?
