You're getting a lot of pushback here, and I'm not sure if you truly don't understand why or if you are trolling/being disingenuous on purpose. Webster's definition of faith:

1

a : allegiance to duty or a person : loyalty

"lost faith in the company's president"

b(1) : fidelity to one's promises

b(2) : sincerity of intentions

"acted in good faith"

2

a(1) : belief and trust in and loyalty to God

a(2) : belief in the traditional doctrines of a religion

b(1) : firm belief in something for which there is no proof

"clinging to the faith that her missing son would one day return"

b(2) : complete trust

3

something that is believed especially with strong conviction especially : a system of religious beliefs

"the Protestant faith"

None of these definitions of faith fit science. Scientific theory is not faith in the slightest. Scientific theories cannot exist without evidence and observation. Faith has no such requirement.
