What you mean by objective?
I literally defined the word immediately after I said it. I will reword it.
Objective knowledge: knowledge which can be applied or obtained by anyone regardless of their beliefs.
So you don't understand the scientific method. The scientific method is only applicable to the physical world.
...
Energy is physical.
No, I do understand the scientific method. The issue here seems to be that either we have different definitions of "physical," or you don't understand energy. I would define physical as anything which exists materially. Energy is immaterial, therefore not physical.
Energy, however, does affect the material world in observable and measurable ways, which is why I can believe in it. In fact, if a deity or any other spiritual being did exist, I would expect them to exist as beings of pure energy, but to my knowledge, no verified or repeatable observation of such a being exists. Neither does there exist any theory for how pure energy could manifest itself as an intelligent entity. With that being the case I remain skeptical of any supposed knowledge about spirit creatures.
Now perhaps I am wrong about this, but if spiritual beings have any impact at all on us physical beings then it seems like there should be some evidence of how they can do that.
How do you scientifically measure the potential of an idea before it's execution? Even dreams have an impact on the physical world.
I don't know... yet. The scientific method has been applied to learn more about the nature of both thoughts and dreams than anyone would have thought possible 500 years ago, so who is to say that it won't one day be capable of that.
I have enjoyed our debate, I believe that debate has value in its ability to make one think and refine their own ideas. I will do my best to examine your arguments, but as things stand now I still see no way for metaphysics or philosophy to prove the existence of a soul, creator, or life after death. I believe that philosophy and metaphysics are tools for introspection, therefore they will only tell you more about who you are as a person, not about the nature of the Universe.
