My House Did not have a Builder (or did it?)

Weird because cleansing with blood makes about as much sense as cleansing with any other toxic material.

It's symbolic of spiritual cleansing.

See, that is how you should read the bible, as literature.  How do you decide when to read it this way and when to start taking everything literally, as you go on to do here:

When we sin, our literal blood becomes corrupted. That's why we all die.

Now you're using the bible as an empirical reference - why?  How do you decide the blood is figurative in the context of cleansing but actually and factually contaminated by sin causing our bodies to die when we would otherwise live forever?

Even if someone never gets sick or died in an accident or anything, if they live to be over 100 years old and are still healthy, they will still die. We are born with a sin nature (meaning that at some point, we will sin, it is inevitable), and we are spiritually dead. And once we actually commit a sin, our sin causes us to die physically (eventually.) And if those sins are not remitted, then we will be judged for them and punished for them.

.. assuming you were correct in your initial guess that the bible is the place to discover stuff about the god you assume exists.  From where I stand it would seem I have no more reason to think the bible is the place for important information to avoid supernatural dangers than I have to believe that stepping on a crack will break my mother's back.  There just isn't anything compelling about warnings regarding the supernatural, a place from all accounts which is completely apart from the real world.  I'll take my chances.
