Biologists and geologists claim through extensive research that the current species of life on the planet, which is estimated to be over 10,000,000 is approximately 0.01 percent of life that’s existed on Earth throughout its existence . We may think that the biodiversity that we have around the world is of an abundance, but that’s simply not the case. Billions of species of birds, insects, mammals, reptiles and amphibious creatures have had their moment, and through one reason or another 99.9 percent of them have gone extinct. We can’t even begin to imagine what was around before we were, and what’s waiting to be discovered deep underground. The age of the Earth is described by scientists as 4.54 billion years old, and the earliest signs of life are proven to have existed approximately 3.5 billion years ago, so I’m sure we can agree that there’s been a lot of comings and goings.
As I have already covered in my article It’s the end of the world as we know it, there have been at least five major catastrophic events that could have potentially wiped out all life on Earth, but life was most resilient and managed to survive these events. The majority of life is found around the Equator where the rainforests are most prevalent, and when the rainforests are destroyed, by natural events or catastrophic events, this is where life is affected the most. Evolution and natural selection over 3.5 billion years has allowed life to adapt to its surroundings and the majority of the time that life has existed on Earth it was very primitive, and was literally single cell. I touched upon this in my article The tree of life. Micro organisms known as Eukaryotes can reproduce asexually, and the more common known types of micro organisms are bacterium and archaeon, and are very resilient. I’ve shared the below image a few times now, but it shows how bacteria can mutate to survive a threat like antibiotics.
Considering the traumatic, Earth changing catastrophes that our planet has endured, it truly is astonishing that life managed to progress to a multicellular level, never mind an abundance of sentient life. If the dinosaurs hadn’t gone extinct, and continued beyond their 175,000,000 year reign over the Earth, where would that have left us and other mammals? Would we have ever co-existed with dinosaurs like the charlatan Ken Ham believes? Yet, only the non-avian dinosaurs perished, and their descendants (birds) flourished. The link between dinosaurs and birds is commonly viewed by scientists as the Archaeopteryx, which was a non-avian feathered dinosaur that was thought to be capable of flight, albeit it limited. The name like you’d expect is derived from Ancient Greek, and is (archaīos) meaning ancient, and (ptéryx) meaning feather.
In my article All creatures great and small, i discusses the diversity of creatures who stray away from the normal standards of survival, and this involves parasitic relationships, symbiotic relationships, and hermaphroditism. Life will mutate and evolve, and even change sex to continue the species’ survival. Some species of animals have no close relatives and other species have many, scientists rate their value on how important they are to the ecosystem. Species with many relatives are often studied closely to try to understand why they’ve been able to evolve so successfully and become so diverse.
Look at Primates, but more specifically human beings. We are an extremely diverse species in that there are multiple races, with thousands and thousands of developed languages. We are a prime example of how successful evolution is, and how living in tribes, or societies if you prefer, is essential for our survival. We are simply greater in numbers. You have to agree that in the two million years since Homo Erectus stood on two feet, and the 200,000 years that Homo Sapiens have evolved, humans have achieved a great many things in their brief existence.
So why do theists believe in a creator, and creationists believe God made Adam and Eve, when there’s clear evidence from fossils that isn’t the case and there have been several variations of humans before us. Why would a God make life so diverse? If the current life on Earth is 0.01 percent of life that’s existed, why did he allow so much death and suffering? Even if we address the ARK and the Great Flood, how has life on Earth become so diverse again? How have humans developed over 6000 languages in such a short time, and separated into several races? Why would God create parasites, symbiotic necessities or hermaphroditism? Why overcomplicate everything? I could write a whole article just asking questions on the absolute lack of logic in believing a God created everything, but that’d be as futile as believing in a God.
