^^ @Rockstar i think you misunderstand some things here.
What t.h. they teach in schools, in the US? Life on earth, Miller experiment, the russian coacervates?

The "creation" of the universe 14 billion years ago was probably not happening for the first time, we just do not know enough yet. The initial explosion of whatever was before (from a superdense collapsing object to some quantum mixture) created mass and energy (which is the same, as Einstein had predicted, and the Manhattan project demonstrated), and time, while cooling down and expanding. There was no mass or energy or time before this.

If you want to know what this beginning was like around 14,000 million years ago, you could read Steven Weinberg's "The first three minutes". Be aware that the concept of "time" or "space" did not exist at this point, which makes the "first three minutes" rather absurd – as Weinberg expects you to understand when you read it.
For us humans, a minute today would have been a minute back then (of course we did not exist back then yet), but for an exterior observer one of our minutes would have been gone in what was a second for him, at that "time".

Since this very hot explosion, by the expansion of the universe the latter has become cooler, and darker. Also what we call time is getting slower ("by the minute", which also gets longer lol)

We have developed in this system after a quite long time, but since we exist here we cannot look at it from outside, or see the outside, if there even is an "outside". We are trapped in mass, energy and time of our peculiar system. There could be a million others, and we will never see or know of them. At least with the knowledge of today.

So, 14,000 million years ago the "universe" began to exist, from itself due to some contraction, or quantum mix beforehand, or a "god", no one can prove.
No suns, no planets nothing, just a very hot expanding mass which not even had 'elements', it was still just too hot for them to fall out of this melange.

Suns began to form appx. 100 million and 250 million years after the initial explosion we call the "big bang", and planets came even later. Life on earth started appx. 640 million years ago, before that there was no life on earth, most probably not even bacteria or any life.
When the earth's crust had formed out of molten lava and lots of meteorites and other 'planetesimals', it became cool enough to bear living organisms.

As the Miller experiment (and lots of others in the later years) proved, what we define as "life" can originate from lifeless "dead" matter. Man can do that, and it also happens by itself. Indeed it did happen by itself, you do neither need aliens nor a god for creating the first life, if some basic conditions exist. Indeed it is inevitable if there is no catastrophy like a big enough meteorite, a sun flare or some other major influence.
And if you give those early life forms enough time, they will specialise, become more complex and adapt to situations and conditions they have to survive in. This is evolution.

We can speculate whether there is some unbelievable mighty being that created this "big bang" explosion alright.
But:
1. If there was such a "being" or god or whatever you call it, it did not create the universe especially to create the earth, birds, bees and mankind. Or Dickinsonia, for that matter.
2. If this being is still there somwhere (or somewhen) outside our system, it has no influence on us, nor can we see or prove it.
3. What happened after the initial explosion could not be planned, nor has it been influenced by anything outside of this system.
4. If we believe in a superior mighty being to have created this universe, it has created billions of billions of galaxies, consisting of billions of suns like our sun, with even more planets, and life. And it will not have created humans/mankind to look like it.

So, this is my more or less educated idea of life and mankind, at the moment.
When the bible claims that the earth is 7500 years old, you can believe it or not. You can believe that man walked with dinosaurs, but then you have to disregard logic, experience and science.
