Like you, I find it much easier to believe that God created the heavens and the Earth than I do the Big Bang theory.
This is a thread diversion. The subject of the thread is Evolution/Biology not The Big Bang/Cosmology.
However, as I recollect my Astronomy courses, in 1924, Edwin Hubble published a paper that proved conclusively that there were galaxies far outside our own, often of greater mass than even our own. From the closer ones precise measurments of mass could be made, size could be made and so on.
Now galaxies tend to come in types and measurements of the nearer ones show a fair degree of consistency between types in terms of size and mass.
Armed with evidence that Galaxy types A are similar to other As and Bs to other Bs and so on, you can put the hypothesis to a test. Atoms release unique spectra of light, Sodium is a convenient element for this btw. It emits two shades of yellow that are close to each other on the spectrum quite brightly and other shades at specific points along the spectrum.
In short, Sodium has a spectral fingerprint. So do Hydrogen, oxygen all the elements in fact.
Moving light sources change color. This is called the Doppler shift. Those moving away at extremely high speeds can even change enough to be a completely different color. Those moving too slowly don't change enough for the eye to notice, but more sophisticated equipment can measure it.
The galaxies that are smaller in appearacne would have to be more distant, IF the observation that local galaxies of that shape are about the same size is correct.
Checking for doppler shift, we find elemental 'fingerprints' and they are mostly redshifted. The exceptions are all close by. The Milky Way Galaxy travels with a cluster of other galaxies and orbit a common point. Some of our neighboring galaxies' orbits are bringing them towards us at present.
The degree of the shift tells us the speed the light source is moving away from us.
So, support is shown. Smaller sized similar galaxies are moving fast from us, the larger sized ones are moving from us slowly. Since there is little able to change the speed of something as big as a galaxy except nearby bigger massed things, the isolated separate galxies have in all likelihood been moving the speed and direction they've been moving at for a long long time.
Now here's the fun part. When you check the speeds and apparent sizes of galaxies the distances as measured by relative visual size and the distances you'd get by assuming the objects started moving away from each other at the same time, match. That is Galaxy A, and it's similar shaped Galaxy B are X light years from us and Y light years away from us respectively. Calculating the speeds A & B have relative to us by their redshifts gets results that confirms the visual measurement estimates of their distance. That is if A is about half as far from us as B is, B's speed away from us is double that of A's.
Conclusion: A and B and the earth were all very close together once upon a time.
And this is consistently found in the measurements being made.
Conclusion: The Universe was once packed together at the same time. It's since been separated by some method that imparted very different velocities ofn various chunks of matter.
That rather strongly suggests an explosion.
However, if wish to dispute this, please start up a new thread. This one is biology.
