If evolution doesn't exist then all animals should have fossils dating back to 4.5 billion years ago, but they don't.
and we have preserved dinosaur hearts that look more like birds than reptiles but okay, go on thinking the way you do because of an old book and refute scientific evidence for no reason
Actually, they have found many modern and extinct animals alike that are fossilized and it isn't billions of years ago. It is around 6 thousand years ago. The soft dino tissue, bacteria and blood cells found preserved. Proves it.
Let's define Science from 1828 -
[
SCI'ENCE,
noun [Latin scientia, from scio, to know.]
1. In a general sense, knowledge, or certain knowledge; the comprehension or understanding of truth or facts by the mind. The
science of God must be perfect.
2. In philosophy, a collection of the general principles or leading truths relating to any subject. Pure
science as the mathematics, is built on self-evident truths; but the term
science is also applied to other subjects founded on generally acknowledged truths, as metaphysics; or on experiment and observation, as chimistry and natural philosophy; or even to an assemblage of the general principles of an art, as the
science of agriculture; the
science of navigation. Arts relate to practice, as painting and sculpture.
A principle in
science is a rule in art.
3. Art derived from precepts or built on principles.
Science perfects genius.
4. Any art or species of knowledge.
No
science doth make known the first principles on which it buildeth.
5. One of the seven liberal branches of knowledge, viz grammar, logic, rhetoric, arithmetic, geometry, astronomy and music.
[Note - Authors have not always been careful to use the terms art and
science with due discrimination and precision. Music is an art as well as a
science In general, an art is that which depends on practice or performance, and
science that which depends on abstract or speculative principles. The theory of music is a science; the practice of it an art. (American Dictionary of the English Language, Noah Webster, 1828)]
As I said afore, might want to learn about the opposition towards your conclusion as there is another conclusion.
