What is out there?
Everything is a system. All systems (except perhaps quarks) are composed of causally related components which are themselves systems. All systems (except perhaps the universe) are part of one or more supersystems. Perhaps all that exists are physical and temporal patterns, ie. information.
What is going on?
Evolution on all scales. The process of variation and selection is not only happening at the level of biological species, but also at the level of cellular development, cognition, human culture, and perhaps even the multiverse if the current theory of inflationary universe is true.
What does it all mean?
Things mean what they cause. The meaning of life in general is in the effects of life. The meaning of your life in particular is the sum total of how your existence has changed reality by influencing, directly or indirectly, the world and people around you.
Why am I here?
The proximal cause lies with your parents. If you are looking for an ultimate cause, you will have to find it yourself but don't let anyone convince you your reason for living is to serve some higher authority.
What should I do?
The most important thing to learn is how to think critically. Constantly question your beliefs, avoid inconsistency, and act rationally. Create a meaningful life by influencing the world around you. (See the Virian sins and virtues.)
The word "virus" has negative connotations for many people so it may seem odd to name a religion after it. The name was chosen to be deliberately antagonistic, to put people on their guard and let them know this idea was designed to infect them. Call it truth in advertising.
