The thought that the Multiverse is real relies on the fact that our Universe is too small to explain many mysterious phenomena, including the astonishing, favorable conditions for the birth of intelligence.
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.
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.
During the inception of our Universe, fortuitously arose a small possibility that under certain circumstances there might come into existence at least a single primitive intelligent being. The planet upon which this would occur remained a mystery, and the emergence of intelligence on Earth is not miraculous. This could have materialized on another celestial body, and a thinking being similar to us would likewise ponder: why us, why here? It's a matter of chance, you're simply fortunate, your planet won the cosmic lottery.
The distant future is richer and weightier than the present, and this signifies only one thing: a fulfilling life now, but in the name of the Human of the future!
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.
