1. Response to the Moral argument

Premise 1: If God does not exist, then objective moral values and duties do not exist.
Premise 2: Objective moral values and duties do exist.
Conclusion: Therefore, God exists.

P1 fails because there are numerous alternatives that can act as a grounds for objective moral values and duties by theist own definition, which is something grounded in a metaphysical theory of everything. For example, instead of being grounded in theism objective morality may be grounded in deism, pantheism, naturalistic pantheism (i.e. atheism), pandeism, acosmism, panpsychism, transtheism, henotheism, polytheism, pastafarianism, or an evil god, just to name a few.

Atheists/scientists can assert an objective basis for morality grounded in Naturalistic Pantheism as a super law of nature or product of a super law, simply one we have not yet discovered. Therefore, like theism, science is also capable of asserting explanations for any apparent objective phenomena such as an objective basis for: morality, purpose, meaning, value, consciousness, freewill, intelligibility, rationality, math, logic, origin of the universe, etc…

2. Response to the Historicity of the bible

If I told you I saw a real living breathing dog, then you should believe me.
However, if I told you I saw a real living breathing unicorn, you should not believe me.

The difference between these two claims is that dogs have an implicit empirical basis, whereas unicorns do not. Meaning for dog there exists many things about them that we can verify in the present such as their taxonomy, bones, genetic makeup, chemical composition, what they are allergic to, etc..; that I simply haven’t mentioned in the argument, i.e. implicit.

Because I have made an empirical claim about the world, it requires empirical evidence that we can verify in the present. The conceptual evidence of my testimony is insufficient to justify the claim unicorns exist because we cannot verify conceptual evidence in the present and you would have to accept something in my memory/imagination is an accurate representation of reality. Examples of conceptual evidence are testimony modern or historical, personal experience, intuition, anecdote, etc.

Therefore, to justify the empirical claim unicorns exist would require empirical evidence of unicorns, where the conceptual evidence of my testimony is only sufficient to justify belief is was a delusion, misinterpretation, imagination, fabrication, hallucination, etc… all conceptual conclusions about my mind.

Historical claims work the same way, if the claims already have an implicit empirical basis then they are, prima facie, reasonable to accept. If they do not have an implicit empirical basis than an explicit basis must be provided before they are reasonable to accept.

Therefore, miracles, magic, mythical creatures, the supernatural, paranormal, aliens, etc… would all need an explicit empirical basis before they were reasonable to accept based on historical testimony/conceptual evidence. However, it is reasonable to believe such claims to be delusions, misconceptions, invention, confabulation, or imagination as those are conceptual conclusions and therefore only require conceptual evidence such as historical testimony.

This principle can be summarized as:
Conceptual claims require conceptual evidence; empirical claims require empirical evidence.

These are my original arguments, which I hope to use to find opportunities to do public debates with theists; check out my YouTube channel for more:
