Have you talked to actual real cosmologists? I suspect you haven't. The big bang theory is our BEST MODEL for explaining the DATA.
How can you explain galactic evolution without positing that the universe was different (younger) many billions of years ago? We can see that the universe was different easily by the types of galaxies that were present.
We know the galaxy is expanding, this is a fact.
The distribution of hydrogen and helium are consistent with a big bang model of the universe.
We can observe clouds of matter which are distinctly different from matter present in active areas of space. These "leftover" remnants are additional evidence of the big bang.
How can you be amazed that cosmologists adapt a theory which can explain all of the above? Can your endless universe model do that? If it can please claim your nobel prize. I don't understand how you can be arrogant enough to make a claim such as yours with no evidence as if it's obvious.

Ah, now I understand why.
