@xingu,
First the shape of the earth!
The Bible described the shape of the earth centuries before people thought that the earth was spherical.
Isaiah 40:22
It is He who sits above the circle of the earth,
And its inhabitants are like grasshoppers,
Who stretches out the heavens like a curtain,
And spreads them out like a tent to dwell in.
The word translated “circle” here is the Hebrew word chuwg which is also translated “circuit,” or “compass” (depending on the context). That is, it indicates something spherical, rounded, or arched"not something that is flat or square.
Second the stars and earth etc.
* The Bible frequently refers to the great number of stars in the heavens. Here are two examples.
Genesis 22:17
Blessing I will bless you, and multiplying I will multiply your descendants as the stars of the heaven and as the sand which is on the seashore; and your descendants shall possess the gate of their enemies.
Jeremiah 33:22
“As the host of heaven cannot be numbered, nor the sand of the sea measured, so will I multiply the descendants of David My servant and the Levites who minister to Me.”
Even today, scientists admit that they do not know how many stars there are. Only about 3,000 can be seen with the naked eye. We have seen estimates of 1021 stars"which is a lot of stars.[2] (The number of grains of sand on the earth’s seashores is estimated to be 1025. As scientists discover more stars, wouldn’t it be interesting to discover that these two numbers match?)
* The Bible also says that each star is unique.
1 Corinthians 15:41
There is one glory of the sun, another glory of the moon, and another glory of the stars; for one star differs from another star in glory.
All stars look alike to the naked eye.* Even when seen through a telescope, they seem to be just points of light. However, analysis of their light spectra reveals that each is unique and different from all others.[1] (*Note: We understand that people can perceive some slight difference in color and apparent brightness when looking at stars with the naked eye, but we would not expect a person living in the first century A.D. to claim they differ from one another.)
* The Bible describes the suspension of the Earth in space.
Job 26:7
He stretches out the north over empty space;
He hangs the earth on nothing.
There is a great deal of scientific evidence that supports the Bible. Enough that we have a separate page to discuss this proof alone.
And than there is the proof of prophecy!
One of the strongest arguments for the accuracy of the Bible is its 100% accuracy in predicting the future. These future predictions are called “prophecies.” The Old Testament was written between approximately 1450 BC and 430 BC. During that time, many predictions of the future were recorded in the Bible by God’s prophets. Of the events that were to have taken place by now, every one happened just the way they predicted it would. No other “sacred writing” has such perfectly accurate predictions of the future.
If you want answers the bible backs its self up!
