Why is it that the universe has such low entropy in the past, resulting in the distinction between past and future and the second law of thermodynamics?

Before the theoretical Big Bang, all energy was packed up into one small pocket, but when the big bang happened the force of it made energy spread, and is still spreading today, eventually to the supposed "Heat Death" that will take place thousands of years from now. This will be due to the law that energy is neither created nor destroyed.
 The entropy increases as it is gradually trapped in the earth, (aka greenhouse effect) is now warming up the earth, causing climate changes.
Hope this helps... :)
