fortunatley the Bible doesnt say that the earth is 6000 years old. It does say God created the earth.
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.
If the Bible states a scientific fact then it should hold up under scientific scrutiny.
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.
people will get offended anywhere they go. I was merely pointing out the it works both ways.
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.
If I dont do that for my (future) children then Ive failed in teaching them about Christ.
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.
This was a big issue and maybe still is. I will check into it as I may have been mistaken if the law finally passed. The govt wanted to force all churches to marry homosexual couples if they wanted the church to marry them. If the churches didnt comply they would lose there tax exempt status
