I was bored today. So I decided I would come up with a very large list of points about why I believe what I do.
Those of you saying that evolution and the Big Bang have no evidence (*cough* pianistimo, *cough*), kindly refute all of these.

Evidence for evolution:
1. We share a considerable amount of genes with every animal. At some point this DNA must have been passed on from a common ancestor.
2. Put some bacteria in a petri dish, it will evolve before your eyes.
3. Genetic inheritance and mutation cannot be denied, the effects are seen everyday.
4. Every living thing must have a parent.
5. White moths were replaced with dark moths. They adapted to fit the darker trees.
6. Humans are gradually getting smarter, taller, and have less body hair.
7. Considerable fossil evidence to show that there were common ancestors.
8. Rock analysis proves that the Earth is at least 4.5 billion years old.
Evidence for Big Bang:
1. The Universe is constantly expanding as per Hubble's law. Recessional velocity of a galaxy is equal to Hubble's constant times the distance.
2. Cosmic Microwave Radiation, fills the Universe. Here is a link for you to learn more:
https://en.wikipedia.org/wiki/Cosmic_microwave_background_radiation#Relationship_to_the_Big_Bang3. Abundance of Primordial elements. Ratio of hydrogen (Atomic Number 1) to Helium and Lithium (Atomic Numbers 2+3) These ratios are consistent with those of the Big Bang models.
4. Redshift between galaxies shows we are all moving away from each other.
Those are the four most important. There are more.
What was before the Big Bang:
HH Initial State: Wikipedia says it best. "More precisely, it is a hypothetical vector in the Hilbert space of a theory of quantum gravity that describes this wave functional." Here's the link:
https://en.wikipedia.org/wiki/Hartle-Hawking_stateString theory: Wikipedia says it simplest again. "String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects called strings, rather than the zero-dimensional point particles that form the basis for the standard model of particle physics." "A version of string theory, called M-Theory, with five curled-up dimensions and five large ones, had a surface similar to our four-dimensional universe. The particles in this model resemble quarks and gluons. " It also advocates p-branes as the structure of the Universe in part.

The foam is a qualitative description of the turbulence that the phenomenon creates at extremely small distances of the order of the Planck length. At such small scales of time and space the uncertainty principle allows particles and energy to briefly come into existence, and then annihilate, without violating conservation laws."
That last sentence is key.
