You believe by faith, for there is no proof. Face it, it's your religion.
I quite like some of the Buddhist arguments about Ultimates (paramattha) in Buddhism, which point to the fact that we believe a lot more than we think:
"Water exists. However, a molecule of water can be subdivided into H2 O, namely, two atoms of hydrogen to one atom of oxygen; therefore, water, as such, cannot be regarded as an ultimate, for an ultimate, by definition, is something that cannot be subdivided.
Once again, an atom is not an ultimate unit, for it can be subdivided into protons, electrons and neutrons. These protons, electrons and neutrons are not ultimates either, for they can be subdivided into atomic particles and muons and quarks, and maybe these are the present ultimates in Science.
There are two kinds of truth, one is conventional truth, like our concept of water, (sammuti-sacca), and there is ultimate truth, like atomic particles (paramattha-sacca).
.... You cannot see an ultimate with the naked eye but only with the eye of wisdom, that can be called the "inner eye", for it is abstract. Similarly, you cannot see an atom or a molecule except with the "inner-eye".
Just pause for a moment to consider that the whole body of water in this universe, the lakes and rivers and oceans are not ultimates; they exist only in conventional language but they do not exist in terms of ultimates.
There are ultimates in Matter (materiality) and ultimates in Mind (mentality), and they are seen by the Buddhist inner eye as having or manifesting properties or qualities. But nothing exists apart form the ultimates.
Each of these ultimates has its individual essence, called sabháva; sabháva is also translated as intrinsic nature. One has to come to realize these individual essences by contemplation or meditation, both the individual essences of the ultimates in Matter and ultimates in Mind.
Mind and Matter can be likened to a Cripple and a Blind Man. The Cripple can’t walk, and the Blind Man can’t see. When the cripple is put on the shoulders of the blind man, the cripple can see and directs the blind man to go left and right.
Mind wants to eat but it cannot eat, and it is the body that eats, Mind wants to drink, but it cannot drink and it is the body that drinks. It is the Mind that controls and directs."
