You've confused me with someone else. As I said, you're welcome to your faith (as long as you don't try to force it on others). While I think it's irrational to insist the Bible be taken literally, word for word, it's a free country. The downside to that belief is it pushes many people into extreme positions, e.g., the Earth being only 6,000 years old and it being created in literally seven days. As the majority of Christians show us, neither belief is required in order to believe in God, nor even to believe God created the heavens, the Earth, and life.
That's fine, you don't have to believe it. If you prefer to believe God created the universe, go for it. From your perspective, science is just saying God created the universe with the Big Bang. Science and God don't have to be mutually exclusive.
Yep, the drawback to living in a free country is you will be offended (see my .sig). America has both freedom of religion and freedom of speech. If you cannot abide that, you should probably be looking for a country with a theocracy. Sadly, the ones I'm most familiar with are Islamic theocracies, but I haven't looked into it.
As far as your children are concerned, I suggest you be truthful. We live in a secular country with diverse beliefs. Tell them they will be exposed to different views and different values. This means other people will be "sinning" according to your beliefs. But also tell them that Christ told you to love the sinner, even if you hate the sin. Tolerance should be a key Christian value.
I will point out one error in your comments. You claim that the government is requiring ministers to marry homosexuals. To the best of my knowledge, that is completely false. While businesses have been required to provide their commercial services to homosexuals, that does not apply to churches.
