This section is to provide the information for questions asked with 'why', in general. The question may arise for any reason and we take the responsibility to answer them logically and if it does not get approved by the reader; may it require further review by the group of logic experts, it would be reconsidered. Absolute scientific definitions are not mentioned in this section which would make specific to the science (otherwise); however, answering is taken from the logical point of view (instead).
Why do we exist?
The fundamental element of this universe is invisible and keeps excerpts of the conceptions (and pre-conceptions) [known as 'samskara' in sanskrit] derived from the information obtained by sensory organs, according to which the structure of mind is established. It all happens spontaneously.
According to nature,
'The subsistence of fundamental element continues unless the 'samskara' are washed away"
Simplification:
Samskara (excerpts of conceptions and pre-conceptions).......proportional to.......Conceptions/Preconceptions.......proportional to.......Information.......proportional to.......Sensory Organs activity.......proportional to.......Structure of mind
Samskara are the cause of continuation of subsistence of the fundamental element and the process of wahing away is very difficult as it requires a lot of patience and wisdom to obtain the right information which is required to make right conceptions, and minimizing pre-conceptions, taking the responsibility to wash away the samskara deposited from the previous subsistences.
Religious Explanation:
This fundamental element is also called as 'soul' in the religious books and continuation of subsistence is called as 'rebirths'. If your deeds are not good and as per the instructions by spontaneity (nature), you are thrown back to various forms of life until and again the human life is taken because its only the human life that has the highest wisdom and intellect to deal with circumstances and their consequences appropriately and performing all the deeds proportionally to keep the harmony with the law(s) of nature which ultimately leads to the freedom of soul and that is the greatest achievement, according to the religious books, called as 'Liberation'.
