If the goal is to convince atheists that gods exist, then it behooves you to present evidence that atheists consider valuable.
But thats the point. The impossible point. Your asking for the impossible. Asking the question in the first place is a category error. You should not even be asking this and realising that it cannot be asked in the first place.
Its not so much about whether there is a God or not but the method by which we measure that. Even Galilao recognised belief belonged to a different realm than science so he seperated them. There were the aspects of reality such as the conscious experiences, pain and pleasure, love, belief ect and there was the quantified apects such as the laws of nature and objective reality.
But one could not be used to measure the other. So asking for material evidence of a immaterial aspect of reality is like asking what is the mathmatical equation for love. You can't even ask the question because it doesn't make sense. Your not even asking the right questions as belief belongs in a completely different paradigm with completely different criteria for what is reality and how that can be understood.
If one wants to believe in one's gods, nobody is stopping one from doing so.
Its not nothing to do with stopping people believing. Rather its making believers conform to a material meausre of belief when belief is not even in the ballpart of material understandings of reality. All we can say is that empiricle science can only measure one aspect of reality which cannot measure belief and other transcedent aspects of reality.
So all we can say is that as far as objective reality is concerned there is no evidence. But there still may be evidence by looking at other ways of knowing reality such as lived reality and experiences. But as science cannot measure this all we can say is that in the greater scheme of things we cannot rule out belief in God as a real possibility.
If you then insist that belief and God can only be measured by material sciences then this is no longer science but metaphysics and belief. Its actually imposing a epistemic condition on how we should know reality when there are other ways of knowing reality.
Thus its more a metaphysical belief being forced upon believers who have their own metaphysical beliefs.
I mean, it is what it is, but I have no conscious experience of any gods. So my third hand experience of what you tell me about your first hand experience is not very useful.
Actually its the most powerful because its direct one person to another. We do it everyday. When people share their experiences we engage, we are there with them. Unless there is obvious evidence to the contrary we usually believe them. We take their word for it.
First hand testimony is what the bible is about. Its what we read about in journals and historical accounts. It actually can paint the color of reality of what happened rather than the black and white qualified data of the event.
I do have firsthand conscious experience of love.
Yes and you believe in that love as being real. But try and quantify it in scientific terms or measures. The moment you do then you lose what love is. Its no longer love.
