As someone that used to be a JW, defending creation and rejecting science, you need to start from scratch Alex.
Ypu wouldn't take an honest approach to learning how satellites worked by copy snd pasting all the flat earth reasoning for why satellites don't really exist,
Don't trust anyone but yourself, everyone has bias and agendas. You can monitor your motivations and bias however, so, if you REALLY want to know the real truth about science and evolution, take the effort to teach yourself. Currently you are just borrowing other peoples arguments and the majority of informed people will tell you, you have been deceived. But don't take their word for it.... learn all the facts and decide for yourself.
This is what I did snd it took years to decipher what I felt was true, I did it via the library and science classes. I am very confident spesking for myself that we have a very thorough understanding of abiogenesis and undeniable clarity on evolution. The big bang is also not just well understood but photographed in real-time, it is an exciting time to have genuine questions however the answers will take time.
Keep in mind what you are attempting to achieve. Abiogeneis is the study of the genesis of living cells and would require years of study in biology, physics and chemistry and advanced degrees is microbiology to fully understand.
The study of evolution, and the progression of genetics over time requires study in biology and chemistry and advanced degrees in biology.
The study of the big bang rewuires study in chemistry and physics and advanced degrees in astro-physics.
The fact that there are people here willing to help guide you through years/ decades of study that they have accomplished means you should firstly be very appreciative, but secondly respect the effort and learning they/we have done and do likewise. Don't just copy and paste what several non academic watchtower writers have written for you to consume. Nobody outside of cults or religious organisations like the JW's likes, needs or wants other people to do their learning and researching for them.
if you are serious about knowing truth..... go find it yourself and put the literature away, if they are right, you will come to the same conclusion as them, so nothing to lose.....
