Of course this is just a different way of defining the verb "exist" but its the same as asking Science whether thought exists.
I read this on this forum
When inventing a god, the most important thing is to claim it is invisible, inaudible and imperceptible in every way. Otherwise, people will become skeptical when it appears to no one, is silent and does nothing." - Anonymous
Not too disimlar to thought. Its subjective, no-one else can hear or see it and it does nothing by itself except that it can become an energy. Thought exists therefore God exists. Those thoughts that relate to IPUs are fleeting and do not create much energy, perhaps the odd joke or two, but thoughts of God can change countries.
In the end the atheism theism debate is boring and defunct. God exists in thought and therefore exists. Its far better to design a better less bloodthirsty God by helping to alter thinking patterns about a perfect God than it is to deny its existence. Whether you like it or not God does exist ie has an energy in this world . Energy has to come from somewhere ie our thought processes.
Of course I'm now waiting for an atheist to ask me to prove that thought exists .
