Our existence on Earth is pointless.

I will now post definitions to clarify the meaning of my resolution. Please no arguing over semantics. If my opponent greatly disagrees with one of my definitions (so much so that he thinks abiding by them will rig his chances in the debate) than he may say so and *offer* an alternate definition. Our existence on Earth: refers to our lives as humans on the planet which sustains us, Earth. Pointless: otiose; serving no useful purpose; having no excuse for being. (1) Contention 1: Life does not add up or lead to anything because all life on Earth one day will cease to exist. There are no reliable sources that can exhaustively account for the existence of an afterlife; therefore, we must conclude and debate around the premise that there is none. If my opponent wants to assert the opposite, than he will be given a chance during his round. It is self-evident that the Earth and all of the existence upon it is bound to come to an end at some point. Scientists heavily speculate the when and the why but there is consensus that the Earth and its inhabitants will cease to exist at some point. Since I am arguing based upon the premise of there being no afterlife, there is no point for an individual to behave a certain way or do certain things (such as schooling, working a job, etc). Social norms and governmental control have dictated this largely but when looking at the bigger picture you will see that it does not matter. Even if your life led on Earth is enjoyable, it will all cease to an end and you will have nothing to show for it after your death; all effort will be in vain. If one is experiencing greater enjoyment or success from someone's past life, then their greater enjoyment/success will too be in vain due to the inevitable end of life and end of existence. Contention 2: Our existence is destructive and if anything negative towards Earth itself. People commit suicide, smoke cigarettes, eat unhealthily, pollute the environment, kill each other, and other numerous destructive and self-destructive acts/habits. Humans produce waste and have no space to put it so bury it into the Earth, polluting soil and creating the possibility of polluting water, food, or plants in the process. When arguing towards the point of human life, one must take into consideration that humans have a negative existence: we undo more than we do. Sure, we have the cell phone that can let you talk to people many miles away or we have the internet that can let you talk to anyone else that has a connection and a computer despite our global distance. However, the Earth was a more natural and pure place before we began to exist. We have not only damaged our own existence but the future existence of those to come on Earth. Conclusion: My definition of pointless is, "having no excuse to exist." Not only do we have no reason to exist in the first place (first contention), we do not even aim to justify our own existence peacefully and healthily (second contention).
