Would you really though?
Yes. That isn't theoretical, it is based on hard experience and great personal cost.
Are you prepared to come to terms that you were wrong about what you believe? Cofty have you considered that you have been lied to about the theory of evolution? I know you are comfortable in believing this theory but how can you know it’s the truth?
Evolution is as certain as the fact that the earth isn't flat. I am an expert on all forms of creationism. I know all the creationist arguments and I understand why they are false. Creationists only ever know their side of the debate and what they have been told about science by other creationists. I have invested hundreds of hours to investigate evolution. It is beyond all sensible doubt. it is only ever rejected on grounds of ideology. Most scientists give as much time to creationist objections as astronomers do to flat earthers. It just isn't an actual question unless you are indoctrinated by Iron Age myths.
what if you believed chance as origin of life for a long time then came to realise actually it must have been intelligent design as the origin of life?
The origin of life is neither chance nor ID. That is a false dichotomy. Also abiogenesis is not the same thing as evolution.
would you then wish you could go back and not know what you now know?
I have never regretted learning new things. Follow the evidence wherever it leads. Anything else is intellectual cowardice.
