Sin is defined as an offense against God. To show something is a sin you would have to 1) know/assume God exists and 2) know/assume that some certain thing offends him.
What might offend God is a theological question that is not usually universally agreed on, if ever. It’s not like waiting for a liquid to turn green for example in a laboratory beaker.
Off the top of my head Christianity and science :
St Augustine theorized that the universe began with time and not in time. Science agrees with this today.
Isaac Newton thought that if God was the master of all the universe and created all nature then nature must be able to be understood mathematically and be uniform across the universe. So the same law that brings an apple to earth keeps the moon in its place. He also thought that it was silly that God was constantly interferring with nature to help it run but that it was more probable that a God would create laws to keep everything in its place. He found out quite a few of these laws and created the basis of modern physics, although his stated hope that it would help people see there was a God did not materialise.
Darwin paraphrased Newton in his book ‘Origin of Species’ when he said it was more probable that the Creator would create life in such a way as to allow it to continually adapt and develop rather than continually personally interfer by making small ad-hoc improvements. Apart from his mentioning about ‘the Creator’ (which evolutionists have quietly distanced themselves from today), his theory is at the heart of modern evolution.
Belgian Catholic priest Father Georges Lemaitre first theorised the Big Bang Theory as the start of the universe, a theory that was derided at the time by the scientific community but now is universally accepted as the basis for the creation of the universe.

Pasteur, in working with infectious diseases rejected the then generally scientific idea that disease (life) was created spontaneously. He believed only God could create life. He looked for and found microbodies and founded the science of microbiology and saved millions through the subsequant industry of pharmaceuticals. He also introduced disinfectants to hospitals and innoculations for certain cattle herds for farming.

The long held Christian position of our nature being a creation that interacts with a deeper realm is currently being validated. With the discovery of Quantum Physics and the realisation that our universe works to a set of probabilities rather than a direct physical ‘cause and effect’ process, scientists today are theorising about possible realms beyond our time and space (and hence our science) that created and continually underpins our natural world.
One theory of course is the ever present Creation theory (Either the 6 day/period or the much more widely held billions year old universe theory), other theories include string theory that connects space across pathways outside of our space and time, another theory is the 11 or 13 dimension theory and another theory still is the parallel world theory where the whole universe constantly splits in two after a quantum event.
In seperate research, because of the almost uncannily lucky relationship between the laws we observe and matter in our universe, other theoretical physicists have proposed that there are an infinite number of universes (beyond our time and space) that go unobserved and we just happen to live in the one that supports existance. Although they are silent on what process generated these multi-universes and assigns laws to them.
Physics in the last 50 years has talked more and more about realms beyond our time and space that not only created our universe but underpins its general workings. This develoment in science is also in line with Christian theology and the materialistic interpretation of science (sprung up in the last 100 years) of our universe simply being a set of matter and laws standing by itself has been abandoned in the higher echolons of physics for at least the last couple of decades.
Happy New Year everyone.
