Life - the point of it's existant

WHAT IS LIFE?
Life is just an energy or a force that keeps living things alive.

How does a human life start?
It started from an sperm being fused together with an ovum. 9 months of growth, out comes a new born baby.

What do we do in life?
When we are young, we learn things. Learn to walk, talk, analyze, do things and develop our own thoughts. We go through ups and downs in life, challenges, attempts that is a success and attempts that is a failure. We interact with other individuals - socializing. We fall in love. Love and Lusts. We make friends and enemies. Know about other cultures. Science and technology plays an important role. We try to make corrections for the mistakes we've done. We do our best in trying to make peace.
When we are categorized under "children", we go to school and learn things. When we are known to be "teenagers", we start to develop our own thoughts and become rebellious because of our strong believe in ourselves. This leads to a straight crash into a steel wall or we might just be able to run into a new world.
People starts to fall in love during the teenager or young adults period. Some are damn successful in wooing. Some just sucked big time in it. Love is in the air. Air is not made of one type of gas. So lust and heartbreaks are also in air. Harmony and disasters. Good and evil. All in the "AIR". So what makes people think that Love is the only thing that they can breath in when they have a partner? Does it mean that they dun breath in the lusts as well? Love goes on from the period of teenage till death. Of course, love ain't just an force of attraction between two sexes (for minority cases, same sexes). Parents care for their child is also know as love. A good friend that cares about you also loves you. A little girl that likes to go everywhere with her lil teddy bear is also love.
At the period of young adult, the more brilliant ones continue their life with further studies. Those less brilliant with books will be forced to go straight into society. Education plus knowledge equals high income. Provided that skill of charisma is not lacking. This statement isn't 100% true. There are people who got drooped out of school cause of poor results yet they've made millions and living the life of a king. Once we are out of the education life, we are for sure committed to be working our ass off and making money to support the family.
Some remained a bachelor for life. Some found their ideal partner in life. and some just simply find a mate that can help them take care of their house and their children. After years of work, then comes the retirement. This would be the time that u will be enjoying the money that you've saved from years of working. Enjoying life till we are stiff and lying in a box.
I still remember a video clip that i used to like. It's an ad from Xbox. The video starts with a pregnant woman that is about to give birth. She pushes so hard that the baby just flew out of the window and traveled the world up in the sky. When the baby was flying up in the air, the baby grew and became an adult and grew old. Just like a projectile motion. What goes up must come down. When that man was old, he just landed straight into a cemetery and straight into a casket in front of a tombstone. It's damn hilarious but if u really analyze the video, life is really too short to be messing around with. When we grow old and we track back what we've been through in life, its like we've only lived 1 week since birth. time flies. time moves forward. Time waits for no one but the rotation of earth.
Life explained with 3 simplified words - Birth, live and die. It goes on and on and on. Till god knows when. This made me wonder. Whats the point of living when we die in the end? Whats the use for learning so much and yet we still need to die in the end.
