I'm going to make an assumption that your question is not actually looking for an answer but I will share my point of view on the topic of your question. 1st. Things have an age. Might be an obvious point to start with but the real differences start with the dating mechanisms that we as people use. To start - human artifacts that are dating to an age of 10K to 15K years old. Carbon dating can be used to date things up to 50K-60K years of age. Even then assumptions MUST be made. Not all the needed variables are known. Known decay rates are easy. Known starting conditions are not. Assumptions about the starting conditions and rates of creation in unknown conditions of the needed elements to gauge the age of objects that absorb carbon. (For more info look up radiometric dating methods *geared towards those who have no idea what I'm talking about*) Basically, assumptions are made about some of these needed variables Some studies find vastly conflicting dates among groups of the same samples that go for dating. These situations do not get a lot of attention but the articles are there for anyone who goes looking. That is one essential aspect of dating mechanisms that NEEDS an answer. Considering the prior point. The dating mechanism CAN give correct ages. It CAN also give incorrect ages. Quiet a problem. Dinosaurs, a global flood COULD be reasons for why many species are not around anymore. Fossilized wood - how long does it take to petrify wood (that is what you meant I'm guessing). It can take ages and it can hundreds depending on the situation that surrounds the felling of that wood and the elements that are present. Geological, astrological evidences that the world and universe itself are pushing billions of years old. Aside from crossing information I'll start with geological evidence - If you mean the Cambrian explosion... you need to ask how they date that strata. It would appear that they date that strata by the age of the fossils in them. So a dating method that has problems is used to date the fossils... and those fossils are in turn used to help date the strata. So the Geological evidences are nearly all suspect. Astrological evidences - The age of things keeps changing with time. In ten years the ages of things will change again. Ten years ago the "Age of the universe" was billions of years different than it is proposed to be today. The real question is why is it so important to you to trash others for what they believe. Is it so wrong to think for yourself? In the end, if those who think that the world is 6K years old and those that believe the universe is 13B years old are both going to die... what happens after that is a good question? No one here truly knows. Some believe one way and other believe something else. Get over it :D

There have been probes on Venus, the Moon, Mars, and Titan. There was a probe sent into Saturn, but thereis no real surface, so that's a special case. There was another that went into Jupiter, but burned up.

the moon, mars, venus (well a molten puddle that once was a human made artifact), titan, possibly some pieces of the galileo probe in jupiter's atmosphere. one asteroid ghas a spacecraft that landed on it. and that is all

Earth and the Moon (obviously), Venus, Mars, Titan (Largest moon of Saturn), and Eros (asteroid).
We have also impacted Comet Temple 1 with a bug hunk of metal. I don't know that its left anything behind that could necessarily be identified as man-made though.

Jchpro is correct. Moon, Mars, at least one moon on Titan, and there is another satellite that left the solar system for who knows where.
Peace

Earth, the moon, Venus, Mars. Soviet Union landed all kinds of probes on Venus, we've landed a few on Mars. We also injected a probe into a comet once, sent one inside of Jupiter, and I think we landed a probe on one of Jupiter's moons.

Hi. Venus, Earth, Moon, Mars, Comet Swift Tuttle (I think), Jupiter (very deep). I think that's it. I do not remember any craft hitting Mercury or the Sun
