What "natural law"? WTF is that?

I don't need to become an expert on trees to be able to tell if they're real or not. And I don't seem to need a book to threaten me with eternal fire if I don't tithe.
The natural laws of the universe which regulate everything. Science is based on it. All knowledge is.
And yet you will never learn a tree is real unless you put in the effort to observe and understand what it is.
I'm an expert on breathing without having studied it. I'm also really good at eating, walking, running, taking a dump, making girls cum... and I never read up on any of it!!!
To claim that science is based on something you made up yourself is pretty funny.

And I have yet to learn that a tree is real? Do you actually re-read what you write before you post it, because that's one of the dumbest things you've ever said.
So science isn't based on observing the natural law of the universe? And you are an expert on things you've never worked at? Seems unlikely.
Let's take say one of your examples. Say breathing. You are lying if you say you've never worked at it. How do I know? Because you breath every second of every day. Otherwise you would be dead (natural law, not mine). And presuming you are the age you act, you have maybe 13 years experience breathing in and out every second of every day. The body has to work hard for that.
And that's assuming your claim to being an expert. Which is hardly true. I doubt you've seriously studied it. Some Buddhist for example study breathing in depth. Focused on mindfulness breathing. Do you even know what that is? Can you tell if your breathing is slightly influenced by sickness before other symptoms become apparent? Do you understand how air enters the lungs or why it works? Do you understand how oxygen is converted to CO2? Do you even know how to tell if you are breathing properly? Have you ever thought about it or do you just assume that since you are still alive you are breathing properly, efficiently, and understand it completely?
My guess is you've.never thought about more than superficially. And you think you are an EXPERT? Men can work all their lives at truly understanding and barely begin to pierce the veil of knowledge on a subject.
This is equally true with all your other subjects. Your presumption that the only effort one can do is reading is equally absurd. Reading just gives us the advantage of allowing ourselves a chance to learn from the personal experiences of others as well as our own.
