What type of living organisms were there?

In summary: We can see evidence for all this in the fossil record, and in DNA comparisons. We can also see the process occurring in real time in bacteria and viruses, with new strains of influenza virus appearing every year, and bacteria that used to be easily treated with antibiotics evolving to resist the antibiotics. That is evolution in action.In summary, the Big Bang theory explains the beginning of the universe, abiogenesis explains the beginnings of life on Earth, and evolution explains the diversity and development of life on Earth. These are separate theories that do not contradict each other and have nothing to do with each other.

Nothing existed before the Big Bang. How could there be any living organisms? Are you talking about the Cambrian explosion instead?

How did we reproduce/evolve from nothing...

We didn't evolve from "nothing"...we most certainly evolved from something.
This topic sounds earily familiar to another thread we had a little while ago where someone was trying to connect the Big Bang to evolution of life. As we asserted over and over in that thread, the BB and evolution are separate topics that have nothing to do with each other.

Of course they're different theories, but they're the most accepted theories in their field, yet they contradict each other.

How do they contradict each other?
The theories discuss two quite different things.
Note that it is possible to have a universe that will not support life or for that matter sun and planet formation.
Since this particular universe has a structure that can support life the discussion of the evolution of life is meaningful.
In some universe structured differently it would not be.

If there were no living organisms before the big bang, how are there living organisms after? How did we evolve from something that wasn't there?
NoTime said:
Okay, I'm not quite sure what your point is here. Both theories are accepted for our universe.

I suggest you actually read the Big Bang theory.
It took a while for the Universe to cool enough to form matter as we know it.
So even in this universe there were no living organisms for quite some time after the big bang.

Evolutionary theory has NOTHING to do with how the universe was created or how life began (two things that happened VERY LONG times apart from one another as well), it only addresses how organisms have changed AFTER life came to exist. The Big Bang theory addresses how the non-living universe started. They are not contradictory and neither is dependent upon the other either. For example, if someone stumbled across some amazing discovery of some other way the universe came to exist that completely refuted the Big Bang Theory, that would NOT dismiss evolution.

I agree... and while you're at it, epkid08, perhaps you should look up abiogenesis as well.

The main point of my topic is not about the theory of evolution or what it states, it's about how can living organisms exist if they had nothing to reproduce from or evolve from, given that "Nothing existed before the Big Bang."

Then look up abiogenesis, as suggested by BoomBoom.
You do realize the Big Bang is about how the universe was created, right? It makes no sense to have it in the question at all.

Try reading this for the formation of life from non-life:
http://www.talkorigins.org/faqs/abioprob/
Of course this assumes that we start off with a young Earth to begin with. If you want to know how we came to have an Earth and a solar system to begin with you might want to read the entire Big Bang timeline till the formation of the planet.s

The framing of your questions indicates that you do not have a good grasp of the theories you're asking about, however.epkid08 said:
As others have pointed out, that is the theory of abiogenesis. Time-wise, Big Bang > Abiogenesis > Evolution
In the very simplest version (you can look up more details in textbooks so we don't have to write a whole textbook here): The early conditions of the universe after the Big Bang were not conducive to formation of life. Lots of temperature changes and chemical reactions happened first, and eventually those reactions led to an atmosphere with appropriate mixes of gases for supporting life, liquid water on the ground, chemical molecules and compounds sufficiently abundant and concentrated on the ground to form life, and those compounds could come together in chemical reactions that would be the first life forms. Keep in mind that living organisms are mainly big bags of chemical reactions happening in an aqueous environment (our cells have a lot of water in them).
At this time, there is no reason to believe this happened only once either, unlike the formation of the universe which is believed to have all occurred from a single event (the Big Bang). If all the precursors and environment were right, early organisms may have formed in many different places from those precursors.
Now, AFTER those first organisms formed, THEN the process of evolution can start. Cells reproducing, mutating, coalescing into colonies, specializations of functions occurring within the colonies, functional specializations becoming more organized into organ systems (plants and animals), and more complex organisms forming.
FAQ: Before Big Bang: Life Before Creation
What existed before the Big Bang?
The concept of "before" the Big Bang is not well-defined in the current understanding of cosmology. The Big Bang theory suggests that the universe began as a singularity, a point of infinite density and temperature. It is believed that time and space as we know it did not exist before the Big Bang, making it difficult to define what existed "before" it.
Was there life before the Big Bang?
The Big Bang theory does not address the existence of life before it. It is focused on explaining the origin and evolution of the universe. Some scientists suggest that the conditions necessary for life may have existed in the early universe, but this is still a topic of ongoing research and speculation.
How was the universe created before the Big Bang?
The current understanding of the Big Bang theory suggests that the universe was created from a singularity, a point of infinite density and temperature. However, the exact mechanism of how this occurred is still a topic of debate and research among scientists.
Can we ever know what happened before the Big Bang?
As mentioned before, the concept of "before" the Big Bang is not well-defined in our current understanding of the universe. It is possible that new scientific discoveries and advancements may shed more light on this topic in the future, but for now, it remains a mystery.
Was there a time when the universe did not exist?
The Big Bang theory suggests that the universe began as a singularity, so it is believed that there was no time when the universe did not exist. However, our current understanding of time and space may not apply to the conditions before the Big Bang, making it difficult to answer this question definitively.
