Using radiometric dating techniques (ratios of elemental isotopes), meteorites, and therefore the Solar System, formed between 4.53 and 4.58 billion years ago.
In terms of the the ratio of lead-207 (from uranium-235) to lead-206 (from uranium-238) from the oldest known specimens found on earth, an age of 4.54 billion years has been calculated.
See the references below:

We deduced the age of the solar system by finding the age of the oldest meteorites (rocks from space that have fallen to Earth). We find the age of a rock by a process called isotopic dating (it has other names, as well). Carbon dating is a type of isotopic dating that uses an isotope of carbon, but is only useful for things that were once living, and even then only for a few tens of thousands of years back. But there are other isotopes of other elements that can be used with rocks.

They do that based on the sun age... With the some techniques they date the age of the old things. The sun and all the solar sistem were criated almost in the same time. To determinate the sun age they estimate the hydrogen and helium taxes at the sun surface.

Science and religion suffer from the same dilemma. Neither can prove the other is wrong.
For them to know the age of the planets would be very assuming.

well i remeber my high school biology...Carbondating etc..but for plants especially for trees i remeber something about cutting the trunk and counting the rings and then doing the math
