"If a tree falls in a forest and no one is around to hear it, does it make a sound?" is a philosophical thought experiment that raises questions regarding observation and perception.
Can something exist without being perceived? – e.g. "is sound only sound if a person hears it?" The most immediate philosophical topic that the riddle introduces involves the existence of the tree (and the sound it produces) outside of human perception. If no one is around to see, hear, touch or smell the tree, how could it be said to exist? What is it to say that it exists when such an existence is unknown? Of course, from a scientific viewpoint, it exists.[7] It is human beings that are able to perceive it.[7] George Berkeley in the 18th century developed subjective idealism, a metaphysical theory to respond to these questions, coined famously as "to be is to be perceived". Today meta-physicists are split. According to substance theory, a substance is distinct from its properties, while according to bundle theory, an object is merely its sense data. The definition of sound, simplified, is a hearable noise. The tree will make a sound, even if nobody heard it. The definition states that sound is a hearable noise. So the tree could have been heard, though nobody was around to do so."
I don't think we can assume, that the Universe was created or just simply something that happened via the Big Bang (BB).
