I remain skeptical in regards to the origin of life as far as whether or not evolution is possible. For one, it is mathematically improbable, something like 1 in 10^132 assuming abiogenesis is possible. We have to get a planet like ours (very improbable) and then get everything to evolve to be more and more complex. Antibodies and resistance aren’t the same as becoming a new species. Also, if you estimate how long it would take to add a new gene that wouldn’t weaken the species (slowing it down or killing off that organism), the Earth isn’t old enough. There would have to be a period or periods where evolution was rapid (missing fossils even though each species supposedly lived for 100,000+ years), and rapid evolution hasn’t been observed anywhere. We also found fossils dated to be millions of years old that show species that are exactly the same as today. Others have gone extinct, and still others are missing too many pieces to definitively tell what the heck it even was (yet they’re prematurely presented as transitional species). Even slow evolution hasn’t appeared in lizard studies or bacteria studies, even in thousands of generations. Scientists have tried to simulate life starting in early Earth conditions, but so far it has been unsuccessful. The first one produced both LH and RH amino acids (poison to life) and newer ones based on updated knowledge of early Earth have produced nothing so far. We can copy DNA or move it to another host, but it hasn’t been able to create itself on its own without an intelligent designer: a human. Sure, survival of the fittest is true. Animals that blend in better have a lower probability of being eaten, and of course if something is eaten it isn’t going to pass on its genes.
I think evolution is accepted because it is the only non-god explanation for life. If we find something else, evolution will be abandoned (except the natural selection parts). Already, scientists are talking about things like parallel universes. The fact that criticisms of evolution are not allowed in our classrooms (nobody is saying anything about God, religion, or an intelligent designer… only criticisms of evolution) should be a huge red flag. Also, more and more scientists are turning creationist or hiding their views because there is a history of people being fired, denied entrance into Master’s or Ph.D programs, etc. if they don’t believe in evolution. It’s not a friendly environment. Many transitional fossils presented have been hoaxes, and they are still classified as some sort of intermediate stage between apes and humans. Scientists are prideful people who continue down a path just so they can keep their grants, even if they know they’re not getting anywhere new.
Another strange thing is the dinosaur fossils that had soft tissues. Even in the best conditions, chemists are saying that the dinosaur couldn’t have lived more than 6,600 years ago. Maybe the Earth is younger than we thought? Maybe dinosaurs didn’t die off as soon as we thought and did co-exist with humans at some point? Maybe we’ll never know?
I don’t think any origin of life studies are truly falsifiable. God is defined as being infinitely powerful and always existing, so there really isn’t anything He couldn’t have created. Evolution is said to be falsifiable if there is lack of fossils. But there are tons of missing fossils (“the movie of evolution is like a film with 999 of 1,000 slides missing”) and that might just be because the conditions weren’t met, not because they never existed. There is no way to tell without a time machine…
