Which questions will remain unanswered by scientists? There are no questions that science will not eventually be able to comprehend and explain, it is only a matter of time. There may be certain details that are not crucial for understanding the overall picture of the world. For instance, perhaps, science may never give an exact answer to the question: How much time has passed before self-organizing matter appeared?, but since that period was the Era of Nothing, the concept of time loses its meaning, and therefore the answer to this question is not so important.
Mathematics does not exist in the Universe as the substance of creation; it exists as a language for describing natural phenomena, playing an informative and descriptive role for us. The magnificence of its equations depends on the whimsicality of the physical world, without which the equations would not be so elegant, and we would not exist.
The existence of such a curious creature as humans suggests the existence of a Universe just like ours. And this doesn't mean it was planned this way or that this is the only possible mode of existence. Reality could have had other properties that would not allow for the emergence of any kind of intelligent beings. Yet, fortunately for us, reality is just as it is.
The evolution factors and mass extinctions in the history of life on Earth point to the absence of a definite aim for the emergence of life and the process of evolution.
What do different currents of thought have to say about God and the universe? Theism — God created the world and manages all its events; Deism — God established the universe but doesn't interfere with it; Panentheism — God includes the eternal universe, and also exists above it; Pandeism — God, upon the creation of the world, became one with it, and is now the universe itself; Pantheism — the universe is equated to God, or is seen as sacred; Atheism — the absence of belief in anything supernatural, or the belief in the existence of nature only; Agnosticism — the answer is not yet known, or is entirely unfathomable.
Beautiful human feelings and emotions were formed in a long evolutionary process, primarily due to love, work, cooperation, and the exploits and hopes of the most ancient and ancient people. If life is joy, love to a human is virtue and pride!
The human race at the beginning of its existence was the result of an extremely favorable confluence of circumstances. However, its further evolutionary development to attain full intelligence would have been impossible without the decisive role of humans themselves.
The ultimate questions about our world: Why does it exist? In what way does it exist? Does it have a purpose? Could it have not existed at all? Could reality be such that no intelligent being would have appeared? Why does it have the ability to give birth to intelligence? Why is the world the way it is? Why is it so whimsical? What is its structure? Is it finite or infinite? Has it always existed or does it have a beginning? Does it have a prime cause? What lies beyond its limits? Is it eternally evolving or destined to decline in the future? Can intelligent beings live forever? Is the world knowable or not?
The origin of intelligence, is it a mandatory and 'inevitable' property of reality? No, it's causeless and spontaneous. Reality could have existed in a primitive form without the self-organizing property. So why does the Universe possess this property, thanks to which intelligence arose in the process of evolution? Just, without a cause. Without this property, no questioning being would have emerged.
