When there is no physical evidence, what made you decide there is or are gods? Do you care about lack of proof? How do you experience this/these deity/deities?
We have five senses, which are sight, sound, taste, touch and smell. Each sense can verify some aspects of reality data. Full reality verification requires that all the five senses be used at the same time. An intimate relationship between man and woman can engages all five senses, simultaneously. Procreation places us in the center of reality. Whereas, looking at the universe through telescopes, only uses the sense of sight for partial sensory verification.
The sense of sight is important in terms of science verification. However, sight alone leaves out the other four senses, and therefore has no checks and balances to fully verify 5-D sensory reality for the animal brain. Einstein demonstrated the relative nature of reference, which is based on using energy/sight. The limitation of one sense, such as sight, can be demonstrated with virtual reality glasses. Computers and technology is showing us how using one sense, even sight, can fool us, if there is no verification from the other four senses.
Belief and proof of God is rarely done by the sense of sight. Belief in God tends to be verified with a subset of the sense of touch. This subset is associated with feelings and body sensations, such as a gut feeling or an intuition. It uses the same number of senses as physics, which is one.
Faith is often done in community, where human contact and intimacy is part of the verifying experience. There you can use your eyes and ears to verify your inner feelings though others. In the case of science, you can also use community feelings of conviction, to verify your sense of sight; peer review.
Physics put almost complete emphasis on the sense of sight, but this single sense choice is 1-D and relative to reference. Chemistry and biology are two sciences where sight is used but also assisted by our other senses, such as touch, smell and even sound. Food Chemistry and biology even adds taste. This is the center of science 5-D reality and should be the foundation, not 1-D verification science.
In summary, just a some people need glasses or contact lenses to see better, there are also aids that can be used to help one feel God; bible. Also, if one sense is lacking, nature has a way to strengthen the other senses. The scientist may not feel properly, so they will have enhanced sight. While the religious may not see as well in terms of nature, but has enhanced feelings and internal touch verification. Both are parts of possible human experience within 5-D sensory reality.
