Human evolution is a theory there's no proof that we really came from monkeys. either our source of water, how water came up in our planet
if the planet was made base on big bang theory explaining.
Words and phrases must have precise operational definitions. All hypotheses must be testable. Evolution is testable. Creationism is not. If you have a "theory" as you say (what you really mean is "hypothesis" NOT "scientific theory") then it must be testable by others independently.
Creationism is testable...
You can test whether the universe is older than 6,000 years... turns out, it is
You can test whether god could create light before creating the sun and stars... or creating plants before the sun (bad idea; god didn't really think this creation plan through)
We have artifacts from civilizations older than 6,000 years!
We have artifacts from Egypt dating across the entire period where a "global flood" is claimed to have killed everyone (i.e. the flood didn't happen either)
We have fossils that are millions of years old!
You can test many aspects of the creation hypothesis, and it fails every test
