I know that these questions where supposed to be rhetorical, but here's what I think(for the purpose of presenting my ideas/the science as eloquently as possible, I will present them in a factual manner)
Why are we here ? why is there existence ? why does the universe exist what is its purpose?
2) what was there before a big bang?
The universe has no purpose, life has no purpose. The universe was created through expansion from a single atom(the "Big Bang" isn't really an accurate description, it's about as accurate a name as the "God particle" for the Higgs boson and it annoyed the scientists then as much as "God particle" does now.), then the energy formed antimatter and matter, which created protons, neutrons, and after the cooling if the universe from its high temperatures, they came together the varying quantities of these in different atoms creating the elements(helium, hydrogen) in gas clouds, leading to the rest of the universe. In short, life as we know it was a series of chemical reactions, physical reactions, and expansion( Fun and mind blowing fact: space has no edge because it's always expanding. Whooaaa, right?
) Any slight differences in temperature, rate of expansion etc. could've completely altered the way the universe developed, whether organisms developed, if they did, whether organs, tissues, etc. and sentient life developed too, not to mention whether earth would have been in its hospitable proximity to the sun or even if planets developed. In short, the universe is an accident. An awesome, mind-boggling accident, but still, an accident. It has no purpose, it just exists by matter of coincidence and the right conditions.
3) What is the meaning of life
Again, life has no meaning other than what you as an individual choose to make of it. As a human being in a planet of 7 billion in a solar system of 8 planets in a galaxy of hundreds of solar systems in a universe with an infinite number if galaxies, there is no master plan and humankind is not particularly special. I guess this fact makes many people unwilling to accept the big bang theory, as it doesn't provide the same comfort blanket/ thing to love and make you feel all warm & special. Also note that scientific theories have a different definition to a "Theory someone has about governments xkcd" and mean something v. likely but there is still a possibility that it isn't true because we don't have ALL the evidence because, obviously, we weren't there and we are still figuring new things out/ proving it.(conditions in the Large hadron collider and the possible finding if the Higgs Boson)
Anyway, sorry for the essay, and believe me when I say I am no scientific genius so that is all my simplified version of a simplified version of a v.complicated process.
