You do realize that all myths are made up right ?
And yes, absolute certainty is absurd. However, just because something is not certain doesn't mean you can't live assuming it is certain.
Actually religion is a myth with followers. Greek mythology, Viking mythology were all religions at their time, after people denied them and converted to other belief, they began to be called myths.You claim Myths are made up but people of those ages didn't think that. Same goes for todays beliefs.
Probably after a several hundred years, all religions we speak of today will be called Myths.
Human has a difference from animals, we question our existance and believing in those stories which pass generations after generations seems like a way to understand the universe for some people. I understand that and respect that. Science on the other hand is the method i believe which is gonna find the absolut answer to the eternal question but I don't believe that my life will suffice for the time required. Therefore I cannot answer the question of if there is a god or not.
There is only one certain thing in life which is death. All other things are uncertain of course you'll live your life by assuming the way you think. For example, I got my own belief which is based on empathy. I deny the dogmas of religions but I am pretty sure a man cannot live without a "code" or "moral rules" or "belief" whatever you name it. If there are some guys out there who don't kill me, just because it's a sin, im fine with that let them keep believing in it.
I also believe that religion is a moral code for people, check it out all major religions say the same stuff basically. Don't rape, don't steal, don't kill etc.
I agree with those, but other stuffs are bullshit,outdated stuff imo.
