Why did the universe have such low entropy in the past, and time correlates with the universal (but not local) increase in entropy, from the past and to the future, according to the second law of thermodynamics?
Any one can solve my question

If you ask ‘why is time correlated with the entropy slope’, you have already assumed it is, which requires examination. The way we define time would presumably mean it is always correlated with processes, and an entropy slope is experienced as a process. However, if you mean that time has a directionality, and that it follows the entropy slope (past to future, low to high entropy) that also requires clarification.
An ordered state will always tend towards greater disorder, almost by the definition of ‘ordered’. But we do not know that the natural state of our Universe is ordered. According to the laws of physics as we understand them, the most likely state of our Universe is close to maximum disorder. If and when the Universe reaches that state, entropy will be expected to fluctuate randomly between close to maximum and a lesser value. Time as we define it, will not have a ‘direction’ correlated with each fluctuation of the entropy value, so logically it cannot have one now.
Either time does not have a direction; or it does, but it is uncorrelated with entropy; or if it does and seems to be correlated, that is contingent (coincident on whatever unknown circumstance produced low entropy in what we call ‘the past’), however it may appear to us.
Hope this help

i have read a little about entropy and i think that entropy is going from good to worse i.e going from arrange to unarrange i.e perfect to imperfect as at the time of big band every think was perfectly arranged and then the bang happened and every thing got worse and worse for example if you build a castle of sand on desert there are extremely less chances that it will again form a castle but there are a lot of chances that it will become a pile of sand so here the entropy of castle is low and entropy of pile of sand is high this tells us that every thing gets from great to worse and so happened after big bang every thing got worse sorry if the answer is not correct as my lack of knowledge in thermodynamics as i study in class 9
