For whatever reason, consciousness arose and evolved in our universe. There are speculations that consciousness is a way for the universe to contemplate its existence and evolution, which makes for a poetic and philosophical logic. The big questions of why life exist and why the universe exist have not been answered by science. The Big Bang which created our universe is a story that began 13.8 billion years ago. Everything that exist now did not exist prior to the Big Bang. So, what existed before Big Bang? Again, science hasn't come up with a clear answer.
We live in a causal and deterministic universe, or so science claims. Causal means every effect has a cause, and only if this is true, we can determine the future state of our universe from the present state. So, if causality is true, and every event must have a cause, what event, then, led to the Big Bang? Some scientists state that Big Bang is the starting point, and everything prior to that is a moot point because science is a way to understand the laws of the universe, and not necessarily to answer questions like what caused Big Bang, and why did Big Bang occur in the first place, these might be questions for philosophy. And, then there are other scientists that claim that our universe was born from a singularity which in turn is the result of a universe that collapsed on itself. And then there are some scientists that feel confident that someday a unified theory of everything will answer these questions.
To summarize - we do not know why consciousness exist. We are also not sure if there are other forms of consciousness out there. We might be rare, or the cosmos could be teeming with life.
So, what is the best way or a reasonably good way to honor your consciousness? I think one good way is by pushing the mental, physical and spiritual frontiers which means constantly striving to do the things that lead to physical, mental and spiritual growth. Often our pursuits in life are determined by what is expected out of us. When we chase after money and degrees, we might be sacrificing our spiritual way of life. It's upto us to figure out how we are going to contribute to our physical, mental and spiritual well being.
