I'm not really sure where to start with this and there's no way I'll cover anything, but I guess I can throw a few things out there.
In my eyes, there is no meaning in life, except for that we give to it. Some people use religion to apply a certain value and purpose, and there is nothing wrong with that. I personally choose not to. The only value I place in life is the prospect that we may very well be the ONLY intelligent form of life, at least in the way we understand intelligence, in the universe. And maybe we aren't. But we could very well be a precious commodity, taking the first steps into the vast unknown; therefore I believe that in some way, there is some value in us. Of course objectively, there is no inherent "worth". But that is why subjectivity is such an important part of us. We think we are important. And we aren't. But this is our reality and we determine our own value. So why shouldn't we see ourselves as valuable, then?
Hrm... To go off of that, I guess. I think as our being *potentially* one of the only intelligent forms of life in the universe, we are in part at least, somewhat responsible towards doing what we can to learn as much as possible beeefoooore we most likely perish. Okay. Maybe not anyone. Free-will is important, duh. And alright. Maybe we aren't responsible for anything, but by some unfortunate (Or fortunate?) chain of events, here we are. Against ALL odds. And the fact we are even able to contemplate these kinds of things such as our existence, is insane. And I make it my personal goal at least to join in on our endless quest for discovery.
As far as some basic things, I'm pretty liberal. Why should I care what gender you want to call yourself, what religion you choose to follow, who you want to sleep with, it's not my damn business as long as you don't make my business YOUR business. Also... can we just all get along, and all that jazz? Let's all gather around the campfire and hold hands... Or... don't. Actually. Gross. But yeah, all the hippy bullcrap I guess that isn't really useful to everyday society.
... That got a bit awkward towards the end but I need to go to bed and felt like I should at least try to generalize some other junk before I interrupt myself. Maybe I'll expand this tomorrow (But I'll probably forget, let's be real.)
