You are contradicting yourself again. You just agreed with me when I said, "Science and religion both present different explanations. Since both explanations can not be true, they are contradictory," yet now you are claiming there is no overlap.
Science and religion both present an explanation for why the universe is here. Thus they overlap.
That is not what I meant by overlap. I meant that that science and religion have mutually exclusive explanations for creation so the explanations do not overlap. In the sense that science and religion both present an explanation for why the universe is here I agree that they overlap.
Yes, but such a thing would be unable to produce any measurable effects on reality. If it did, after all, then we would be able to measure those effects and thus show that it exists, which would violate the "cannot be shown to exist" part of your claim.
That is just a claim, that the spiritual reality would produce 'measurable' effects on physical reality and in that way we could show that spiritual reality exists. I believe that the spiritual reality definitely does affect the physical reality, but not in ways that are objectively measurable.
Baha'u'llah explained the Purpose that for which the Messengers of God have been sent, to prepare all men for life in the spiritual world. He then explains how the sanctified souls who have passed on to the spiritual world profoundly affect this world.
“The purpose underlying Their revelation hath been to educate all men, that they may, at the hour of death, ascend, in the utmost purity and sanctity and with absolute detachment, to the throne of the Most High. The light which these souls radiate is responsible for the progress of the world and the advancement of its peoples. They are like unto leaven which leaveneth the world of being, and constitute the animating force through which the arts and wonders of the world are made manifest. Through them the clouds rain their bounty upon men, and the earth bringeth forth its fruits. All things must needs have a cause, a motive power, an animating principle. These souls and symbols of detachment have provided, and will continue to provide, the supreme moving impulse in the world of being.” Gleanings From the Writings of Bahá’u’lláh, p. 157
Moreover, there are planets outside our solar system that cannot be 'shown' to exist, yet they exist. Being able to
show something exists is not what makes it exist, something either exists or does not exist. That also applies to God.
And I can use the same logic to show that we should not dismiss the existence of leprechauns.
You could use that argument by my oh my are you going to be surprised when you die and realize that spiritual reality actually exists. Christians refer to it as heaven but there is also a hell even though it is nothing like the Christian hell.
