But it's a made up theory right? There's no solid evidence. I could come up with a story just as easily as to how the universe came to be. How is there a super compressed atom that just come from no where to create an entire universe?
"
But it's a made up theory right?" To start off, please refrain from using the vernacular definition of "theory" when discussing science. It makes you look really uneducated and misinformed- note this is a heads-up for future discussions, don't get offended.
Generally, there are laws and theories.
Theories are proposed explanations for observed phenomena; they are derived from
observations and evidence.
They explain "WHY?"
Examples: Theory of Evolution explains that the similar but different patterns found in species of different environments is
caused by adaptations.
Climate change theory explains that the rising sea water levels and carbon emissions is
caused by greenhouse effects.
While laws seek to describe the relationship between phenomena.
They predict. They don't explain why or what causes it
Usually represented with an equation.
Examples: Thermodynamic and Entropy laws
Newton's law: equal amount of forces
E=mc^2
Plug in for variables, and now you can predict the outcome of an experiment
"How fast will this ball travel at x and y?"
"Will sound travel faster in x or y?"
You're saying that our universe came from another universe that compressed and released itself causing a Big Bang cyclically. So where does the original universe come from? When does the cycle start?
What are you putting your faith in? Your whole ideology is revolved around the Big Bang theory. But the theory itself doesn't make sense.
The theory that earth evolves around the sun is also just a theory right? What evidence do you have for that? Why do you agree with it?
Is climate change just a theory as well?
Even theory of relativity?

For starters:
These are the four pillars of the Big Bang
1. The Expanding Universe:
galaxies appear to be moving away from us at speeds proportional to their distance. This is called "Hubble's Law," named after Edwin Hubble (1889-1953) who discovered this phenomenon in 1929. This observation supports the expansion of the universe and suggests that the universe was once compacted.
---- The fact that galaxies are receding from us in all directions is a consequence of this initial explosion and was first discovered observationally by Hubble. There is now excellent evidence for Hubble's law which states that the recessional velocity v of a galaxy is proportional to its distance d from us, that is, v=Hd where H is Hubble's constant. Projecting galaxy trajectories backwards in time means that they converge to a high density state - the initial fireball
-Redshift occurs when light seen coming from an object that is moving away is proportionally increased in wavelength, or shifted to the red end of the spectrum.
- Cosmological redshift is seen due to the expansion of the Universe, and sufficiently distant light sources (generally more than a few million light years away) show redshift corresponding to the rate of increase of their distance from Earth.
2.The Cosmic Microwave Background Radiation (CMBR)
if the universe was initially very, very hot as the Big Bang suggests, we should be able to find some remnant of this heat. In 1965, Radioastronomers Arno Penzias and Robert Wilson discovered a 2.725 degree Kelvin (-454.765 degree Fahrenheit, -270.425 degree Celsius) Cosmic Microwave Background radiation (CMB) which pervades the observable universe. This is thought to be the remnant which scientists were looking for. Penzias and Wilson shared in the 1978 Nobel Prize for Physics for their discovery.
-Telstar satellites with microwave receivers measure noise interference from multiple sources at the SAME frequency.
3.Nucleosynthesis of the light elements (Abundance of helium and hydrogen):
The abundance of the "light elements" Hydrogen and Helium found in the observable universe are thought to support the Big Bang model of origins.
Prior to about one second after the Big Bang, matter - in the form of free neutrons and protons - was very hot and dense. As the Universe expanded, the temperature fell and some of these nucleons were synthesised into the light elements: deuterium (D), helium-3, and helium-4. Theoretical calculations for these nuclear processes predict, for example, that about a quarter of the Universe consists of helium-4, a result which is in good agreement with current stellar observations.
The heavier elements, of which we are partly made, were created later in the interiors of stars and spread widely in supernova explosions.
-The Big Bang predicts about 72% of the material out there is hydrogen, and 28% is helium. Astronomers have found that about 24% is helium and 76% is hydrogen.
This complies with this theory.
-Later, the heavier elements were created in stars and spread via supernovae and exist in vastly smaller amounts.
4. At about 10,000 years after the Big Bang, the temperature had fallen to such an extent that the energy density of the Universe began to be dominated by massive particles, rather than the light and other radiation which had predominated earlier. This change in the form of the main matter density meant that the gravitational forces between the massive particles could begin to take effects, so that any small perturbations in their density would grow. Ten billion years later we see the results of this collapse.
- This is the framework for the creation of galaxies.

I understand all of these replies & your point of view makes sense. But the simple fact is that I just have a hard time trusting mankind's interpretation on such a massive scale after realizing one of mankind's key flaws & trying hard (often slipping) to fix it in myself. I guess I don't have much room for optimism or trust anymore. Makes me feel old :-/
I'm glad I got my point across. Your pessimism isn't inherently wrong though; I do believe all speculations and theories should be scrutinized.
To end on a good note, it's evident that our endeavors have payed off within the last millenias. From the moment a caveman decided it was productive to use sharp metal alloys to overcome their first challenge- the big bad bears.
The advent of genetic therapy, vaccines, sterilization(especially this) all have facilitated healthier and more accessible living.
Average lifespans going up (medicine), world hunger going down (GMOs), declining death tolls (both from war and living), more renewable and efficient energy sources (nuclear, solar, wind, etc energy). It's easy to get saturated and take all of this for granted.
