No, I don't mean speciation. We believe many species evolved from relatively few 'kinds' (definition from the original Hebrew and ancient Greek) on Noah's ark. For example, all cats may have come 2 cats on Noah's ark - or perhaps a few more kinds of cats. Personally - I think all cats are related by descent - most can also interbreed which would normally mean they are of the same species - but finding an accurate definition of species is just as difficult as an accurate definition of "kind."Macro evolution is a misleading term. I believe you mean speciation and yes, speciation has been observed. That would remove it from false speculation.Evolution is a fact
God is a theory
Micro-evolution is a fact.
Macro-evolution is false speculation with zero observational evidence.
Many beliefs about many gods are not based on convincing evidence but one Greek word used in defining faith in Hebrews 11:1 means 'convincing evidence."
See Romans 1:20 which involves all branches of scientific research.
What branch of thermodynamics is addressed in Romans 1:20?
We do not believe humans came from apes or ape-like ancestors - we do believe extinct races have a common origin to current races- e.g. Neanderthals. We believe Acts 17:26 is accurate and that all races/nations/ethnos come from a common origin - this is proven in genetics. In fact, more recently genetic evidence confirms all races come from the mitochondrial Eve and the Y-chromosomal Adam.
On your other question - the 2nd law of thermodynamics (in fact all heat flow) is observed by the study of things made as Romans 1:20 invites us to do - which actually involves all branches of scientific study.
More specifically Job 38:33 refers to the laws which govern our universe - that would include the laws of thermodynamics.
The law of conservation of matter and energy tweaks the laws of thermodynamics. Heat flow is oversimplifying. One could assume that thermodynamics leads to zero energy - this is simply not true. The only way to remove energy from our universe is to convert it into matter according to E=Mc^2.
While this clearly happened during the origin of our universe, it is rare now. Usually it goes in the opposite direction - from matter to energy - this is what stars do!
Bottom line - the energy in our universe is currently increasing while the matter in our universe is decreasing.
Of course, that ignores dark matter and dark energy - I doubt these are constants but I am not aware of the current scientific evidence as to whether either dark energy or dark matter is increasing or decreasing in our universe or if it is constant. Isaiah 40:22,26 implies increasing - but this is because the Biblical model points to dark/invisible energy coming from outside our universe - i.e. that our universe is not actually a closed system - though this is neither proven nor disproven. Ordinary matter and energy do appear to be in a closed system in our universe. This, of course, assumes our universe is not interacting with another universe.
The origin of our universe does involve an open system since the singularity had a huge input of energy from outside the singularity.
Unless, of course, you believe in the mythical teaching that the vast amount of energy at the origin or our universe came from nothing!
What is a "kind"? Creationists have identified kinds with everything from species to entire kingdoms. By the narrower definitions, variation to new kinds has occurred. By any definition, we would not expect to see biological evolution in time frames of months. Creationists have never hinted at, much less shown, any mechanism that would limit variation. Without such a mechanism, we would expect to see kinds vary over time, becoming more and more different from what they were at a given time in the past. Further, the notion of Noah’s p,ensure cruise and a 6,000 year old planet is absurd. There’s no other way to define it.
Why would you think the universe started from nothing? That’s a description that is a part of the fundamentalist ministries but has nothing to do with the best evidence that science has proposed.
