After reading the process of human evolution, people who think that the theory of evolution is a lie in the scientific community will naturally think:

So, isn't evolution a lie...

Without the Hand of God, how did LUCA, the common ancestor of life 4 billion years ago, come about?

Without the existence of the Hand of God, the 800-million-year-old Ediacara fauna would not have become extinct, how could there be a later trilobite prosperity, let alone the domination of early marine arthropods.

If there is no hand of God, how can you explain the explosion of Cambrian creatures?

Without the existence of the Hand of God, how could there have been an Ordovician mass extinction 445 million years ago, allowing early fish to dominate the oceans?

How did humans start with bugs and evolve step by step to what they are today?

If there was no hand of God, why did the late Devonian mass extinction, which occurred 355 million years ago, preserve the early terrestrial vertebrates?

If there was no hand of God, the Permian mass extinction 250 million years ago, why did the ancestors of dinosaurs and mammals quietly survive?

If there is no hand of God, why would there be, the Cretaceous mass extinction 65 million years ago, clearing the way for human evolution?

How did humans start with bugs and evolve step by step to what they are today?

Without the existence of God's hand, how could nature change the climate again and again, and how many coincidences occurred, allowing ancient apes to come out of the forest and evolve into humans?

SO, the hand of God definitely exists.

Since the hand of God exists, the process of ancient apes evolving into humans can also be avoided, because God can completely skip the ancient apes to create people!

This is typical, theologizing the unknown, and explaining everything that has not yet been explained by God.

For example, when the human fossil system is incomplete, theologists attack evolution in this way. When the fossils were unearthed continuously, it began to be said that the Cambrian explosion must be God's handwriting. But in fact, the Cambrian explosion can have many scientific hypotheses. Even if the truth about the Cambrian explosion is eventually discovered, theologians can have more to do to attack the theory of evolution. Because, the known is finite, and the unknown is infinite.

What is known, can never explain the unknown.
