Science is just based on theories
Well I can't disagree with you there however perhaps your apparent lack of respect for these theories is I suspect due to your lack of understanding of the meaning of the word theory in science.
In common usage "theory" can be equated with a mere casual thought whereas in science to gain the qualification of "theory" is just so much more than you understand the word to mean.
To make it simple where you read "theory" when used in science, for example the Big Bang Theory or The Theory of Evolution, you are perhaps better placed to substitute the words.."established fact based on rigorous testing and providing testable predictions which if not met causes the whole theory to be rejected, presented in a scientific paper presented for review, rigorous criticisms, by other scientists in that field who absolutely enjoy destroying the life time work of someone else so as to be recognised as top dog in that particular field"...sure it's a mouth full that's why they use one word to mean all that and that word is theory. Personally I would use another word ..Perhaps a rock solid fact..however science sadly uses a word that casual passers by think means brain fart.
You really make such a huge mistake demonstrating you do not know what the word means in science that your credibility totally disappears such that folk will not even bother to discuss any matter further with you.
Now it's not all bad as you now know what you reject and hopefully my post provides a turning point in your understanding.
What you will find helpful is to read the notes in Wiki under Carl Popper re the Philosophy of Science and although having read that short entry you will be embarrassed by your uninformed comment you will at least understand what a theory means and enjoy having found the foundation of future wisdom.
Read Popper but here is the wiki entry to help you understand why folk will think you are stupid when you are so ignorant of the meaning of theory.
A
scientific theory is an explanation of an aspect of the
natural world that can be
repeatedly tested and verified in accordance with the
scientific method, using accepted
protocols of
observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an
experiment.
[1][2] In circumstances not amenable to experimental testing, theories are evaluated through principles of
abductive reasoning. Established scientific theories have withstood rigorous scrutiny and embody scientific
knowledge.
[3]
The meaning of the term
scientific theory (often contracted to
theory for brevity) as used in the
disciplines of science is significantly different from the common
vernacular usage of
theory.
[4][Note 1] In everyday speech,
theory can imply an explanation that represents an unsubstantiated and speculative
guess,
[4] whereas in science it describes an explanation that has been tested and widely accepted as valid. These different usages are comparable to the opposing usages of
prediction in science versus common speech, where it denotes a mere hope.
The strength of a scientific theory is related to the diversity of phenomena it can explain and its simplicity. As additional
scientific evidenceis gathered, a scientific theory may be modified and ultimately rejected if it cannot be made to fit the new findings; in such circumstances, a more accurate theory is then required. That does not mean that all theories can be fundamentally changed (for example, well established foundational scientific theories such as
evolution,
heliocentric theory,
cell theory,
theory of plate tectonics,
germ theory of disease, etc.). In certain cases, the less-accurate unmodified scientific theory can still be treated as a theory if it is useful (due to its sheer simplicity) as an approximation under specific conditions. A case in point is
Newton's laws of motion, which can serve as an approximation to
special relativity at velocities that are small relative to the speed of light.
Scientific theories are
testable and make
falsifiable predictions.
[5] They describe the causes of a particular natural phenomenon and are used to explain and predict aspects of the physical
universe or specific areas of inquiry (for example, electricity, chemistry, and astronomy). Scientists use theories to further scientific knowledge, as well as to facilitate advances in
technology or
medicine.
As with other forms of scientific knowledge, scientific theories are both
deductive and
inductive,
[6] aiming for
predictive and
explanatory power.
The
paleontologist Stephen Jay Gould wrote that "...facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts."

All the best.
