Personally, I believe that scientists in the future invented a time machine. Unfortunately, it was only possible to send single cells through time safely. Any larger form of life would simply be destroyed. The scientists sent single cells back to the time before life existed on Earth and those cells eventually evolved into all life that we know of today.
I realise that my tenses are a bit messed up, but that's because this has already happened... Just in the future.

You're allowed to believe whatever you want.
It's a nice belief, but think of it this way: if "creating something out of nothing is impossible' then the atoms that exist in the cell being sent back had to be in the earlier time. So, you're asking for the same things to be in different places, which is the impossible part.
More, while your belief can be made consistent, once one assumes that the cells were sent back, you are sending back order into chaos, and the natural progression is from order to chaos, so, you're reversing thermodynamics.
No: time is unidirectional - always towards the future. Much as we'd like time to be at least bi-directional, we can't get there, at least not until we have a science that isn't dependent on the dimensions of mass, length and time.

Then some scientists even more in the future saw what a mess we'd made of the whole business and went back and destroyed the cells so we don't exist.
There's 2,100 year old science, 150 year old science, fudge trying to accommodate the two and neurotic fantasy.

time problems result in "paradoxes" that is impossible situations
look up the difference between a "theory" that is a good scientific guess based on some evidence and a "belief" a guess that is true by definition
