Sorry, but gonna have to pick you apart - especially on the geology stuff. No offence 😀
Sorry, but we did evolve from apes, just not the apes that are around today. The common ancestor from which both humans and modern apes evolved was still an ape...just a different one. But the point you were trying to make is good.
Plenty of evidence for the Big Bang, especially the microwave background radiation. Ok, some of the physics is a wee bit dodgy (inflation theory) and only seems to be there for mathematical convienience, but there is no other explaination. I think time will eventually supply the missing answers
Carbon dating only works when you have carbon and for ages <20,000 years due the short half life of carbon. You cannot actually date a fossil. However, you can date volcanic rocks above and below fossils. You can also date metamorphics, but they are unlikely to be near to a fossil! Common dating methds for the geologic timescale are K-Ar, U-Pb, St-Nb and other decay similar decay series. These are generically known as radiometric dating.
Only relative dates though. This bit is older than this bit, etc, etc. No absolute ages can be obtained. You need radiometic dating for this 🙂
I seem to remember that this has nothing to do with evolution...I'll have to check where I read this though. I think it was "Almost Like A Whale" by Steve Jones...
Some good points in there...just a wee bit of mis-information 😀

When people say that we evolved from apes, that is totally wrong scientifically.
We did not evolve from apes. We just have a common ancestor with the apes, and somewhere down the line we evolved from them (the common link/ancestor, not ape).

Do I believe in the"BIG-BANG"? No. There just isn't enough evidence supporting it.

Geologic evolution is two. Tectonic plates, theories of pangea, deposition of sediments, calculating the age of fossils via carbon dating all support this.

Correlation is three. This is different layers of rock that show different ages of specimens of life perserved in sediment. Correlation by the comparison of rock layers can produce fair dating of fossils.

For example, if you take a look at the embryos of FISH, CHICKEN, PIG, and HUMAN, you will notice that there are similiarities between them and how they start out which suggest they do have a common ancestor.
