No, Earth isn't the smallest planet.
Earth is the fifth largest planet in our Solar System. It is larger than all the other inner (or 'Rocky') planets (Venus, Mars and Mercury) but smaller than the 4 outer planets (Jupiter, Saturn, Uranus and Neptune) .
Mercury is the smallest planet despite the fact that a multitude of smaller objects orbit the Sun. This is because the definition of 'planet' requires the object be within a certain size bracket, Mercury is the smallest object that fits the required criteria.
These smaller objects are either 'dwarf planets' (a group containing Pluto and Ceres among others) or 'Small Solar System Bodies' which is everything else including comets, asteroids and trans-Neptunian objects.

The Earth is much newer than the universe.
Here's what had to happen before we could have any planets:
-- The big bang occurs and there is a rapid expansion.
-- Universe cools enough for space and energy to decouple.
-- Universe cools some more, enough for elementary subatomic particles to form.
-- Protons and electrons find each other in the soup, start hooking up, and form hydrogen atoms.
-- For some unknown reason, wrinkles develop in the immense cloud of hydrogen so that it's no longer homogeneous. The big cloud starts to break up into smaller clouds.
-- The smaller clouds feel gravity, and get smaller and smaller, eventually packing
together rather tightly. So tightly, in fact, that the pressure in the center becomes quite enormous.
-- Such enormous pressure, in fact, that individual hydrogen atoms in the center
are forced to merge. That releases energy, which pushes outward, resists the
gravity, and stops the cloud from compressing any further. You have hydrogen
fusion, and stars ! The stars eat up their hydrogen, making helium
-- When some of the largest stars end their lives, they explode as supernovas.
The shocks of the explosions create heavier elements, which get sprayed out
into space from the torn apart stars, as dust, which mixes with the hydrogen
that's still everywhere.
-- Like the clean hydrogen did millions or billions of years earlier, the dusty, dirty
cloud wanders and drifts around, and eventually is brought together by gravity,
in places where it's a little thicker than in other places in space.
-- This cloud drifts, roils, and boils for another few million years, getting smaller
all the time under the influence of its own gravity. The lightest stuff in it ... the
hydrogen ... packs into the center, and another new star ignites. But this one is
surrounded by a smoky, dirty cloud made of all the leftovers ... the heavier dust.
-- With gravity still at work, even the dust slowly sticks together in spots, which
become motes, which become sand, which becomes stones, all in orbit around
the young star. As the stones sail through the dust, they begin to sweep it up,
and they become rocks, which become boulders, which grow to asteroids, which
continue to collide, smash, pulverize, and collect again ...
-- Until finally, most of the dust has been gathered together in fair-size clumps.
The region of space surrounding the star is relatively clean, and there are now
a relatively small group of serious-size bodies in orbit around the star.
This star has planets !
That's what had to happen first.
-- The time since the big bang is estimated at more than 14 billion years.
-- The sun, Earth, and the rest of our solar system all round off to about 4.6 billion years.
No. The Earth is the 6th largest and 6th most massive object in the solar system.
By Diameter
By Mass
We believe that the proto-Earth collided with another planet perhaps as large as Mars, about 4.3 billion years ago, and only a hundred million years or so after the formation of the Sun and the solar system.
That "proto-Earth" planet would have been entirely destroyed, with the Earth being formed out of the combined mass. We believe the Moon was formed soon after, from the material blown back into space by the collision.
No, that is not likely. The Solar System - including Earth - is less than half the age of the Universe; it seems that stars formed fairly soon after the beginning of the Universe (say, within the first billion years or so), and it is likely that many of those have planets.
The universe is about 13.5 billion years old (various estimates range from 12 to 15 billion years, and I doubt the accuracy of estimates that claim more than one decimal place) while our solar system is about 4.5 billion years old.
No, Earth is the 3rd planet from the sun.
The 8th planet is Neptune.
Earth is slightly larger that Venus. It's diameter is about 650 kilometres greater than Venus, or about 403 miles.
In comparison with the thousands of solar systems in our galaxy, the Earth is minute - no, it's even smaller than that. It is about 8,000 miles in diameter.
Our Earth was created 4.567 billion years ago and the estimated age of the entire universe is about 15 billion years.
The universe is 13.7 billion years old & Earth is 4.5 billion years old.

Matter cannot be created or destroyed it only changes forms. They are all the same age.
Earth was the center of the universe
The geocentric modelof the universe stated that the earth was at the centre of the universe.
The universe is 13.7 billion years old & Earth is 4.5 billion years old.
Because you're comparing it to the universe. Compare it to a grain of sand and it looks massive.

The Universe didn't even exist for such a long time; the age of the Universe is estimated at about 14 billion years.500 billion years ago, planet Earth didn't exist.

Multicellular life forms have only existed for roughly one-twelfth of the total age of the Earth.
Universe: About 13.8 billion years ago.Solar System: About 4.6 billion years ago. More details at the Wikipedia articles "Age of the Universe" and "Age of the Earth". The details include a discussion about the evidence.

The universe then the sun then the earth:)
Before some things, but not before all things. The Solar System (including the Earth) has an age of about 4.6 billion years ago; some other stars are quite a bit older. The Universe formed about 13.8 billion years ago; many "other things" have this age, or almost this age. For example, many galaxies are almost as old as the Universe.

A universe of joy
No, because there is no universe that begins with Earth.
The universe's shape is unknown, therefore we cannot tell where the earth is. but compared the the universe the earth is a tiny tiny speck
