Do you ever wonder why we're here?

Answer 1

What is our purpose - if any? The philosophy of Judaism is that this world is a purposeful creation by God, in which all people are tested concerning their use of free-will. We possess a soul which lives on after the body dies and is held responsible for the person's actions. Anyone who is worthy, Jewish or not, can merit reward in the afterlife.
Also:

• 1. God exists, and is the Creator.
  

This tells us that the world is not chaotic or the result of chance. Life is the work of a deliberate, purposeful, intelligent and kind Creator; not a melancholy chaos or a string of fortuitous accidents. God is at the center of reality and the center of our world-outlook and thoughts.

• 2. God is eternal.
  

This includes the belief that God's ways are also eternal. God is not capricious, forgetful or fickle. Investing in a relationship with God is the only thing that will bear eternal benefits.

Answer 2

Why do humans respond emotionally to beautiful sights? And why are painters, sculptors, or musicians motivated emotionally (even beyond monetary need) - to create works of beauty? We are created in the image of God (Genesis ch.5), and God himself is a master artist, who (we intuit) enjoys beauty and has made this beautiful world (see Genesis 1:31). The best human efforts to create beauty are a pale reflection of God's own designs. We respond to them because we are made in the Creator's image.
God made the Earth for people: "He did not create [the earth] simply for nothing," but "formed it to be inhabited" (Isaiah 45:18). He wanted people to exist in order to have someone to love, and to give us an opportunity to achieve godliness. All people are tested concerning their use of free-will. We possess a soul which lives on after the body dies and is held responsible for the person's actions. Anyone who is worthy can merit reward in the afterlife. When the righteous use their free-will to obey God despite His being hidden, they have shown that they deserve His love. Their reward will never cease. But even the undeserving are given the kindness of life in this world, and the lifelong ability to draw near to Him.See also the Related Links.

It’s one of life’s greatest mysteries, isn’t it? Why are we here? Are we the product of some cosmic coincidence? Or is there really a god, y’know, up there, with a plan for us and stuff. I don’t know, but it keeps me up at night.
