Your, mine and our consciousness has nothing to do with the existence of anything around (chair, table, building, a cute girl) or in the whole universe. "We're all star dust" - Carl Sagan.
Just like the Sun, core of stars is a nuclear furnace but unlike the Sun's core, these cores manufacture heavier elements C,O,N,Fe etc.and when these stars die and go supernova all these elements are spewed into the cosmos. Hence, C in the wood of chair, table, Fe in the steel of building; N in the amino acid of that cute girl all came from some stars that went supernova million and billions years ago somewhere in cosmos. Let's make it more interesting, N in the amino acid of her one hand might have come from different star of different galaxy than of her other hand !
C,H,O,N elements from star (that went supernova) reaches earth -> simple molecules (like RNA,DNA) forms undergoes self replication -> amino acids (protein) -> single cell organisms -> multicell organisms -> .........billions years of evolutionary history....-> humans. Theory of evolution, Origin of species, how some became extinct and how some evolved over time, is better explained by Charles Darwin. Happy B'day to him.

Universe and everything within it doesn't care whether humans have conscience ! There are fundamental laws governing the Universe. Laws of Physics, call it Laws of Nature if you please.
Our conscience has only evolved since approx. 200K years ago when Homo sapiens sapiens originated and started to evolve. Compare this timeline with the age of Universe. Human species developed much larger brain (of many other things) than other primates (closest cousins chimps and gorillas). Ability to use all the sense organs to interact with the environment, and larger brain gave added advantage over other species. All of this religion, philosophy - couple of thousand years old. Btw, philosophy and religion tried to answer most of the ancient human curiosity, but with the advent of science they sound stupid (at least to me). They are not progressive ! All of the advancement in science and technology couple of hundred years old. Most recent hi-tech stuff couple of decades old.

Some fun facts - With approx. 200K years of history, humans have ruled the earth with class and style. Thanks to brain and science. This is crazy ! Dinosaurs ruled the earth for over 250 million years, they didn't do shit over that time. They didn't use science, nor they had brains like ours. Perhaps they had only Conscience !
