If you want to prove the existence of the world from a scientific standpoint...
I look around and observe the evidence of it's existence.
show me how the Laws of Thermodynamics in regard to matter being unable to return to it's pre-transient state allow for matter to exist and conform as we have it today from nothing.
No one with any understanding of physics is claiming that matter or energy came from "nothing". The concept of "nothing" becoming "everything" is the province of creationist whackadoos who can't be bothered the learn the science that they are attempting to argue against.
You can't win an arguement against the facts so you have to make up a twisted and out of proportion strawman and attack that instead. Typical creationist tactics, the warfare of cowards.
To do so is to argue that matter is eternal, and we all know that just isn't so.
No we don't know that that isn't so, you claim it isn't but you provide nothing to back that up. The Big bang theory postulates that everything that comprises the universe was at one point collected into a superdense sigularity which then expanded, it makes no claim as to the nature of matter or energy at or before that moment, and it certainly doesn't state that it all came into existence ex nihilo, ideas such as that are the province of creationists.
There can only be one other reason, and that is a Designer.
There could be a near infinite number of other reasons, of which a designer is but one. You are narrowing down the field to a designer because that is the one that you want to be true, not because you have eliminated all other possibilities using the scientific method.
In summary all you have acomplished is to attack a grossly distorted and obviously false strawman of Big Bang theory, asserted that the only other option is your "god", and then declared yourself to be the winner. That's not how scientific discourse works.
