What are we human beings really doing here on Earth or why are we alive?

This question is very simple but complex from deep analysis. Traditionally, the genesis of our journey here is from the interaction between a man and a woman as friends or husband and wife. They both raise us up to the age of eighteen or twenty five years depending on the culture and the willingness of the kids to move on and become independent. Post this era, many events begin to unfold, some of our children become very successful, some are killed, some go to jail and some are just onlookers. If you are lucky to be successful, you buy good cars, build or buy good houses, marry and have children. Some of these marriages end up in divorces with many broken hearts. Sometimes, some of the children are successful, some are headache and others are just liabilities. Eventually, we die and our circle is completed. Before we die, there are a lot of messages from religions that if we act right we will end up in heaven with no hardship and everyone is equal in God's image. Is this not a hoax? Why can't the government in heaven not introduced to Earth? If heaven is such a great paradise, why did we wonder to this planet known as Earth? What have we really accomplished on Earth apart from hustling day in and day out to pay bills and accumulate wealths that we all going to die and buried in one outfit. In some mean culture, they burn you to ashes and they sweet call it, cremation. The question again is this, why are we here on Earth? Welcome to provocativedebate.com.
