Hmm well, because humans have the capacity to create goals, create points, and purposes ( neo purposes ). We have the ability to think about thoughts, AND we have the unique ability to think about others feelings and thoughts as well, which lends to empathy, compassion.

I understand why the why or what is troubling, I have often found myself in the same thoughts. There is also the idea that the less religious we become, the more moral we also become. Now that is not a usual concept or idea. Statistics do support this idea tho. But why? Why do we care, why do we have morals, or more morals with out religion? Tho there are some good explanations for this. Maybe we are moral beings after all. We have also evolved beyond pure natural selection I think.

Tho this topic will get you confused and fast, asking what the purpose is, or the point? And accepting evolution doesn't really go hand in hand to smoothly with these questions right? Because they stem from two different ideas.

There is tho always room to change our perceptions. What happens if you try to drop the what is the point, and just focus on what I am now, where I am now, just now.

The dx is still newish to you, and to them. But really people will think what they think, but what you think is what matters and will make the difference to you. If it makes it worse that others do not seem to understand, then there must be a reason why it matters, must be some point in that to you. So maybe there is some point in there after all, or you might not care at all ? It might not have any effect then.

We are very complicated creatures in a complicated environment, given simple explanations. That is how I feel about it.

I don't think you are wasting resources. It could be that if you were not using them, no one would, or they would be wasted for something we don't need, quite possibly you will use them and contribute to something that is needed and you might not realize it, or maybe later you will.

Sorry just trying to help, but I really understand your thoughts about this. Mindfulness can help you to stop some of that over thinking and rationalizing. Should be called something else since mindfulness is quite misleading, the purpose of it is not to fill the mind.
